How to Send Money on Cash App

How to Send Money on Cash App

Toll Free : - +1-866-900-0603

Cash App is now offering routing and account numbers so that customers can deposit their stimulus check directly into their Cash App account balance. Those who didn’t file taxes last year can enter this account information on the IRS website.
With that said let’s take a look at How to send money on cash app. You must trigger your free Cash Card via Cash App to see your account and routing numbers. The physical card should arrive within 10 business days, but customers can start using their Cash Card as soon as it’s ordered by adding it to Google or Apple Charge or use the card info found on the app’s Cash Card tab. Keep in mind the funds held by Cash App are not insured by the FDIC, so they’re not protected in case the company fails.

As more people embrace the convenience of cashlessness, tech companies have made it easier to send and receive money instantaneously from a smartphone. One of these apps, Cash App, has increased in popularity, providing some unique features compared to other money transfer solutions, such as investing in stocks, having special bonuses with “cash boosts,” and buying and selling bitcoin.

Things to consider about Cash out on Cash App

There is a fee to use a credit card. Cash App charges 3% of the transaction to send money via a linked credit card. Compared to other money transfer apps, this is a relatively normal fee; for example, Venmo also charges 3 percent for sending money with a connected credit card. To avoid this fee altogether, use your linked bank account or the funds in your Cash App account to send money.
https://preview.redd.it/g588zp4hlcf51.jpg?width=864&format=pjpg&auto=webp&s=1cf381074fd6370c37e9e8e2e48acadd3d106b68
There are spending limits on the Cash Card. The maximum that can be spent on your Cash Card is $1,000 per day and per week. The maximum that can be spent per month is $1,250.
There are withdrawal limits on the Cash Card. The maximum amount that can be withdrawn at an ATM or store register cash-back transaction is $250 per transaction, $250 per day, $1,000 per week, and $1,250 per month.
Your funds aren’t FDIC-insured. If they encounter “Cash App transfer failed” that means there is certainly a problem. Cash App’s functionality may walk and talk a bit like a bank, but there is a clear distinction between the app and a bona fide, bank-chartered financial institution. Despite the fact that the Cash Card is issued by FDIC-insured Sutton Bank, customers’ funds in Cash App are never transferred or held with Sutton Bank and therefore don’t receive FDIC insurance.
The Cash App is an 8 MB sized payments app currently having 7 million active users who use this application for transferring money and paying monthly bills. This application was developed by Square Inc which also allows its users to invest money in the stock market and Bitcoins effectively in a few simple steps using the app. However, many people who are new to this app find it difficult initially to receive and send money on Cash App. If you are wondering how to send money on Cash App then you can learn it in a few easy steps below.
If there was an easier way to transfer cash from one person to another than Cash App, we ‘d definitely share it with you but we definitely haven’t found it yet.
This simple app lets users transfer funds with just a few taps on their smartphone screen, once you’ve linked an active bank account to the app.

Here’s how to send money to someone on cash app.

Help with an old wallet?

I’ve picked around this problem for over a year now but now I really want to get to the bottom of it. Around 2016, sometime within that year I bought some bitcoin to make a one time purchase not knowing that years later bitcoin would skyrocket versus when I bought it, it was only a dollar and some change per bitcoin. I want to know if anyone with some experience be able to tell me the chances, the odds of finding that old wallet. I know I made the purchase from my phone via QR code so to narrow it down it’s on one of the apps offered for iPhone iOS. If I remember correctly I have a little over ~3 bitcoins that I’ve completely forgot about. I’d love to know everyone’s input, even if it shoots down my hopes.

Weekly news review (July 27-2)

Weekly news review (July 27-2)
How have you been? I guess it's time to deep dive into last week's news.
https://preview.redd.it/5meikrws4le31.png?width=1200&format=png&auto=webp&s=1b2264d3023fc564a88c4da6a7b54ef4624f5c24
The Kazakhstan government has once again issued an advisory to all major local Internet Service Providers (ISPs) asking them to make it mandatory for all their customers to install government-issued root certificates on their devices in order to regain access to the Internet services. The root certificate in question, labeled as "trusted certificate" or "national security certificate," if installed, allows ISPs to intercept and monitor users' encrypted HTTPS and TLS connections, helping the government spy on its citizens and censor content. In other words, the government is essentially launching a "man in the middle" attack on every resident of the country.

Crypto derivatives platform FTX has perhaps the most speculative and oddly-named futures index fund on the market: SHIT-PERP, or the Shitcoin Index Perpetual Futures.
An index of 58 low market cap coins, SHIT-PERP includes projects like Waves, Grin, and Nano. It is flanked by two other low-cap indexes on the site, MID-PERP and ALT-PERP.
Regardless of the index’s name, FTX stands by its product which it launched in June. Speaking to CoinDesk, FTX Chief Marking Officer Darren Wong said the index allows traders and investors to interact with coins in an innovative way. Wong listed three examples:
If you want exposure to a particular initial coin offering, but not the general industry, you can short SHIT-PERP. By shorting the greater alt market, you hedge your bets and limit your downside.
If you want to short low market cap altcoins in general, you can use SHIT-PERP. The indexed future is one of few ways to short low cap alt markets.
If you think bitcoin’s dominance is too high, you can buy all three of FTX’s altcoin futures indexes and sell BTC-PERP, the platforms Bitcoin futures index.

The United States National Basketball Association (NBA) and its affiliated union — the National Basketball Players Association (NBPA) — have partnered with Dapper Labs of CryptoKitties-fame to release a new crypto collectibles game.
According to an official announcement on the NBPA website, the upcoming game is scheduled to launch in early 2020.
The game, called NBA Top Shot, will be a roster-building competitive game that is based on crypto collectibles. According to the announcement, fans will be able to gather live footage of NBA games that can then be used in some capacity to build a competing roster for the game — or to simply be owned and trade as a collectible, as the user chooses.

Fortaleza, a major city of northeast Brazil, will start accepting Bitcoin (BTC) as payment for bus tickets by the end of 2019.
A local transportation service announced an initiative to allow citizens to pay for bus tickets by credit and debit cards as well as Bitcoin and other cryptocurrencies. The initiative purportedly aims to reduce operational costs in the bus ticketing system, the report notes.
The entity, called Cooperative of Independent Transport of Passengers of the State of Ceará (Cootraps), said that passengers will be able to pay for their trips with Bitcoin through their smartphones by scanning a QR code, as first reported by Brazilian tabloid newspaper O Povo.

An iMessage vulnerability patched by Apple as part of the 12.4 iOS update allows potential attackers to read contents of files stored on iOS devices remotely with no user interaction, as user mobile with no sandbox.
The security flaw tracked as CVE-2019-8646 was discovered by Google Project Zero security researcher Natalie Silvanovich who reported it to Apple during May.
The proof of concept Silvanovich created works only on devices running iOS 12 or later and it is designed as "a simple example to demonstrate the reach-ability of the class in Springboard. The actual consequences of the bug are likely more serious."

Money Loves Security And So Do Cryptos: A Brief Guide Down Crypto Wallet Lane

Since time immemorial people have been keeping their money and valuables in safe places. Be they purses, clay pots full of coins buried in their backyards or treasure chests hidden in caves with piles of bones strewn around to keep unwanted visitors at bay, they means conceived for safekeeping hoarded valuables are just as creative as they are limitless.
The advent of cryptocurrencies as a new class of valuables and assets instantly spawned the need to keep them safe from the clammy hands of criminals. The logical solution was to develop wallets that would be used to keep cryptos safe. As a result, a multitude of wallets have emerged offering all kinds of added services to their users while remaining means of storage at heart.
There is a huge variety of wallets available: Coinomi, GreenAddress, Blockchain.info, Atomic, Exodus, Jaxx, Electrum, Copay, Bread, Airbitz, Armory, Mycelium, Blockchain Wallet and dozens of others, each offering their services to suit any taste.
https://preview.redd.it/tai1ax5q3u341.jpg?width=1200&format=pjpg&auto=webp&s=0a33622327c7e52eea02e77f7c843423e6aeba12

Types Of Wallets

There are several types of wallets available to users and everyone must decide for themselves which one suits their needs best.
Hardware wallets: These are the most secure and reliable wallets available, since they are not connected to the internet at all. Hardware wallets are like flash memory cards that store the user’s cryptocurrencies and access offline. A bright example is the Trezor wallet, which is deemed to be impermeable to hackers. Unless the user loses the device itself, it is safe to assume that the cryptos will stay on it indefinitely and no one will ever gain access to them.
Online, Web or Hot wallets: These are online services, or online wallets that offer to store the user’s cryptos online with direct access to the internet at any time. In essence, online wallets are online accounts in which users store their funds. The risks are very high, since exchange wallets are routinely being hacked and the cryptos stored therein stolen.
Desktop wallets: Desktop wallets are software programs that can be downloaded and installed on a PC and will only be accessible from the device they were downloaded onto. The risks are the same as with hot wallets and another added inconvenience is that loss of the device or loss of access to it means loss of all cryptos stored on it.
Mobile wallets: Mobile wallets are software programs that can be downloaded onto a mobile device, such as a phone or a tablet. There are wallets for Android and iPhones and all of them bear even greater risks than hot wallets. Since mobile devices are susceptible to theft and a variety of viruses, it is extremely risky to store cryptos on them. Though access to the cryptos without private keys is impossible, unless the user stores them on the device, loss of all cryptos with the mobile device is guaranteed.
Paper wallets: Paper wallets are offline cold storage for cryptocurrencies. This is by far the safest means of storing cryptos, which includes printing the public and private keys on a piece of paper and storing it in a safe place. The keys are printed in the form of QR codes for convenience. With paper wallets, the user has complete control over their funds and the only risk lies in losing the piece of paper with the keys.
Other types of wallets: Apart from the five main types of wallets, there were attempts at creating other types of services, such as atomic wallets using atomic swap technology and even combinations of mobile/hot/cold wallets. Despite limited success, hybrids models of wallets did not become popular.

Main Pros And Cons

When looking at wallets and their main advantages and disadvantages, it is easiest to speak of the division between cold and hot wallets.
When speaking of cold wallets, such as the Trezor Bitcoin wallet and Ledger Nano S or X, the same issue will be observed, and that is the fact that such wallets can be physically lost. Though anyone who ever finds them will never be able to gain access to the stored cryptos without the private keys (unless they are pasted on the device), loss of all cryptos on the device is guaranteed. In addition, cold wallets can be difficult to install and are inconvenient for frequent use.
https://preview.redd.it/ff2dukdx3u341.png?width=1021&format=png&auto=webp&s=f36cdc26b13f33433c5124f5e5a67c0e40f9dbf4
Hot wallets are far more susceptible to risk than their cold counterparts. Though hot storage is much faster and convenient with a wide variety of options from Coinbase to Blockchain.info, the risk of cybercrime runs high. Mobile or desktop storage is also considered to be hot storage and is also risky, if the device is damaged or destroyed.

Bitcoin Problems

Bitcoin, as the firstborn cryptocurrency, was born with a number of defects. One of the main problems of the king of cryptos is the yet unsolved scalability problem. This refers to the limit on the amount of transactions the Bitcoin network can process due to the limited size of and frequency of blocks in the Bitcoin blockchain.
Said problem poses some difficulties to all Bitcoin users and leads to what is known as backlog in the blockchain. The backlog leads to long queues of transactions in the system. With the average transaction time in the Bitcoin blockchain being around 7 transactions per second and the theoretical maximum standing at 27, it is not difficult to understand how long users of the blockchain have to wait for their transactions to pass in times of heightened demand – the time is in the hours and sometimes even days.

Bitcoin Wallets Review

Since Bitcoin is the most popular cryptocurrency on the market, it is logical to judge wallets by their support of the first cryptocurrency. As such, the following will be a brief review of some of the best and most popular Bitcoin wallets on the market.
Online Bitcoin Wallets
Online or web wallets are the most popular ones out there and the best Bitcoin wallet overall is widely considered to be Blockchain.info, which is easily accessible and convenient for everyday use with good security. As an anonymous Bitcoin wallet, Coinbase follows in the lead with its ability to store a multitude of various coins, but with the same security risks that are inherent to all hot wallets.
Android Bitcoin Wallets
Android is the most popular mobile system in the world and plays host to a number of good mobile wallets. The best Android Bitcoin wallet is widely considered to be the Electrum Bitcoin wallet with its excellent reputation, good security and convenience. Though Electrum has some occasional glitches, they are never critical. Another excellent wallet for Android is the Coinomi wallet with its support for a wide variety of cryptos and excellent user support, which even allows for restore options using special phrases. Coinomi has its issues as well, such as occasional exchange glitches, but the many pros outweigh the cons.
Bitcoin Hardware Wallets
The undisputed leaders as the best hardware wallets for Bitcoin are Ledger Nano X and S, Trezor T and Trezor One, and Keepkey. Bitcoin hardware wallets are comparable in their security, accessibility and usability. The difference is mainly in the price, which ranges from $165 for Trzeor T to $59 for the Ledger Nano S model. In fact, the Ledger Bitcoin wallet is often called the king of hardware wallets. The KeepKey Bitcoin wallet is the in the top three hardware wallets as a convenient and stylish device. Though KeepKey supports over 40 assets, it still lacks coin support.
Bitcoin Wallets For iPhone
iPhone’s iOS system is the second most popular for mobile devices in the world and has support for some good wallets as well. The best iOS Bitcoin wallet for iPhone is considered to be the Abra software, which offers credit card support for topping up crypto balances and a good user interface, which is even more oriented at exchanges. The next software is Edge, formerly known as Airbitz. The Edge wallet is best known for high security and good user-friendliness along with multi-currency support.
Bitcoin Wallets For Windows
Bitcoin wallets for PC are very popular and Windows is leading the way with some excellent offers for wallets. Atomic is by far the most advanced and the best option for Windows users as it offers Atomic swaps technology as its basis. The application offers a wide variety of operations and supports over 300 cryptocurrencies. Exodus is the second most popular choice as a desktop only wallet with support for Bitcoin and many other altcoins. Exodus offers its users a good interface and it is free for use.
Bitcoin Wallets For Mac
Since Atomic and Exodus are cross-platform wallets, they can be used on Windows and Mac. Apart from them, there are also Jaxx and Electrum, which can be used on Mac. Jaxx is a multi-currency wallet with support for around 40 cryptos and has a PIN feature. In addition, Jaxx is free for use. Electrum is one of the oldest desktop wallets and is a lightweight wallet that does not require the full blockchain to operate, meaning less storage needed for its operation. The wallet requires a PIN and is essentially a desktop bank with good security and usability. Electrum is also a Bitcoin wallet for iPad, since it can be used on mobile platforms.
Bitcoin Paper Wallet
Since storing cryptos online on exchange or hot wallets or even on devices is risky, it is oftentimes more convenient to use a simple printer to print out the keys and store them. BitAddress offers a convenient and easy to use, step by step guide to creating a paper wallet with the added benefit of sleeping in peace, known that nothing and no one will ever threaten your Bitcoins.
https://preview.redd.it/bh7wi0d64u341.png?width=600&format=png&auto=webp&s=9f7fbd269eea43ac3b8897ad470553ba8b3c730d

Checklist

When embarking on the journey of creating your first wallet, think well of which type to use. The type will depend on the priorities that stand before the user. If security is paramount, then paper or cold storage wallets are the go-to solution. If frequency of use is the name of the day, then hot wallets and their inherent risks are the best way to go.
The most frequent questions related to wallets are how to add money to a Bitcoin wallet and how to set up a Bitcoin wallet. Both questions have no single answer, as each wallet offers its own instructions on how to top up balances and how to set them up. Therefore it is recommended to study all instructions carefully prior to operation.
Either way, there is no silver bullet and some features will have to be sacrificed in deciding how to store cryptocurrencies. The one thing that is constant is the need to store Bitcoins and cryptos and make use of them.

My experience with the iOS wallet

  1. First I wanted to send some Nano from my nanowallet to the iOS wallet. Couldnt scan the QR code of my iOS wallet with the nanowallet. Therefore representive names like e-mails, like PayPal has is crucial! Had to sent the xrb address of the iOS wallet via Mail to my desktop pc to copy paste in the address in nanowallet. After that I received the transaction in under 10 seconds! Very nice!
  2. Then I wanted to sent some Nano from the iOS wallet back to the nanowallet. When you click on Receive in the nanowallet, you have to type in the amount you want to receive before a QR-Code is created. Why is that? Not very convenient. I know this isn't part of the iOS wallet and of the team but a lot of people use the nanowallet, so this is also kinda your "problem".
  3. The QR-Code scanning took about 10 seconds. This is too long. I had QR-Code scanning experiences on other apps where its instant. After that the screen got black for so long (30 sec.) that I decided to quit. I havent sent the Nano back to the Nanowallet yet. I will try again later.
  4. The design of the wallet is kinda alright but nothing really special. I am a design guy so I have an eye for that. Look into screenshots of the ethos app here! . This looks super slick and is more state-of-the-art when I comes to design with gradients etc.
I know this is just a start for mobile wallets but you gotta understand one thing that is absolutely essential. When Nano finds mass adoption, the web wallet will be the main gateway "normal" people will interact with this technology. They dont care about block lattice, nodes etc. So you better make sure the experience they have with this technology via the mobile wallet is 100% perfect by then.
Hope this helps, thanks for the testflight invite. Im a big fan of Nano and believer. Really appreciate the hard work you guys are doing. Keep it up. On your way to change the world for the better :)
Edit: Tested on iPhone 6s 64gb, newest firmware update.

Update on my barber shop merchant project

Update on my barber shop merchant project
An update to my earlier post describing how I want to set my barber up to accept crypto.
I could not find a simple POS (point of sale) app for merchants that works with crypto. Coinbase Commerce does have integrations for several shopping carts, but I want something simple where my barber can click on a button and then the customer scans a QR code to send the payment. So I hard-coded a simple website that he can display on a tablet:
https://cryptoformerchants.com/
This uses simple Coinbase Commerce buttons. I can't test it yet because Coinbase put a 6 day hold on my bank transfer - ridiculous! The money left my Wells Fargo account the next day. I'm curious how long it will take the transaction to confirm.
UPDATE: The buttons do not appear to work on my iPad. Crap. Works on my iPhone though, weird.
UPDATE 2: Someone clicked on the TEST button and paid me $1. Thanks. But for some reason Coinbase said only $.98 was received?

A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency, you will need to have a digital wallet.
How do they work?
Millions of people use cryptocurrency wallets, but there is considerable misunderstanding about how they work. Unlike traditional ‘pocket’ wallets, digital wallets don’t store currency. In fact, currencies don’t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain.
Cryptocurrency wallets are software programs that store your public and private keys and interface with various blockchain so users can monitor their balance, send money and conduct other operations. When a person sends you bitcoins or any other type of digital currency, they are essentially signing off ownership of the coins to your wallet’s address. To be able to spend those coins and unlock the funds, the private key stored in your wallet must match the public address the currency is assigned to. If public and private keys match, the balance in your digital wallet will increase, and the senders will decrease accordingly. There is no actual exchange of real coins. The transaction is signified merely by a transaction record on the blockchain and a change in balance in your cryptocurrency wallet.
What are the different types of Cryptocurrencywallets?
There are several types of wallets that provide different ways to store and access your digital currency. Wallets can be broken down into three distinct categories – software, hardware, and paper. Software wallets can be a desktop, mobile or online.
Are Cryptocurrency wallets secure?
Wallets are secure to varying degrees. The level of security depends on the type of wallet you use (desktop, mobile, online, paper, hardware) and the service provider. A web server is an intrinsically riskier environment to keep your currency compared to offline. Online wallets can expose users to possible vulnerabilities in the wallet platform which can be exploited by hackers to steal your funds. Offline wallets, on the other hand, cannot be hacked because they simply aren’t connected to an online network and don’t rely on a third party for security.
Although online wallets have proven the most vulnerable and prone to hacking attacks, diligent security precautions need to be implemented and followed when using any wallet. Remember that no matter which wallet you use, losing your private keys will lead you to lose your money. Similarly, if your wallet gets hacked, or you send money to a scammer, there is no way to reclaim lost currency or reverse the transaction. You must take precautions and be very careful!
Although Bitcoin is by far the most well-known and popular digital currency, hundreds of newcryptocurrencies (referred to as altcoins) have emerged, each with distinctive ecosystems and infrastructure. If you’re interested in using a variety of cryptocurrencies, the good news is, you don’t need set up a separate wallet for each currency. Instead of using a cryptocurrency wallet that supports a single currency, it may be more convenient to set up a multi-currency wallet which enables you to use several currencies from the same wallet.
Are there any transaction fees?
There is no straightforward answer here.
In general, transaction fees are a tiny fraction of traditional bank fees. Sometimes fees need to be paid for certain types of transactions to network miners as a processing fee, while some transactions don’t have any fee at all. It’s also possible to set your own fee. As a guide, the median transaction size of 226 bytes would result in a fee of 18,080 satoshis or $0.12. In some cases, if you choose to set a low fee, your transaction may get low priority, and you might have to wait hours or even days for the transaction to get confirmed. If you need your transaction completed and confirmed promptly, then you might need to increase the amount you’re willing to pay. Whatever wallet you end up using, transaction fees are not something you should worry about. You will either pay minuscule transaction fees, choose your own fees or pay no fees at all. A definite improvement from the past!
Are cryptocurrency wallets anonymous?
Kind of, but not really. Wallets are pseudonymous. While wallets aren’t tied to the actual identity of a user, all transactions are stored publicly and permanently on the blockchain. Your name or personal street address won’t be there, but data like your wallet address could be traced to your identity in a number of ways. While there are efforts underway to make anonymity and privacy easier to achieve, there are obvious downsides to full anonymity. Check out the DarkWallet project that is looking to beef up privacy and anonymity through stealth addresses and coin mixing.
Which Cryptocurrency wallet is the best?
There is an ever-growing list of options. Before picking a wallet, you should, however, consider how you intend to use it.
Bread Wallet
Bread Wallet is a simple mobile Bitcoin digital wallet that makes sending bitcoins as easy as sending an email. The wallet can be downloaded from the App Store or Google Play. Bread Wallet offers a standalone client, so there is no server to use when sending or receiving bitcoins. That means users can access their money and are in full control of their funds at all times. Overall, Bread Wallet’s clean interface, lightweight design and commitment to continually improve security, make the application safe, fast and a pleasure to use for both beginners and experienced users alike.
Mycelium
Advanced users searching for a Bitcoin mobile digital wallet, should look no further than mycelium. The Mycelium mobile wallet allows iPhone and Android users to send and receive bitcoins and keep complete control over bitcoins. No third party can freeze or lose your funds! With enterprise-level security superior to most other apps and features like cold storage and encrypted PDF backups, an integrated QR-code scanner, a local trading marketplace and secure chat amongst others, you can understand why Mycelium has long been regarded as one of the best wallets on the market.
Exodus
Exodus is a relatively new and unknown digital wallet that is currently only available on the desktop. It enables the storage and trading of Bitcoin, Ether, Litecoins, Dogecoins and Dash through an incredibly easy to use, intuitive and beautiful interface. Exodus also offers a very simple guide to backup your wallet. One of the great things about Exodus is that it has a built-in shapeshift exchange that allows users to trade altcoins for bitcoins and vice versa without leaving the wallet.
Copay
Created by Bitpay, Copay is one of the best digital wallets on the market. If you’re looking for convenience, Copay is easily accessed through a user-friendly interface on desktop, mobile or online. One of the best things about Copay is that it’s a multi-signature wallet so friends or business partners can share funds. Overall, Copay has something for everyone. It’s simple enough for entry-level users but has plenty of additional geeky features that will impress more experienced players as well.
Jaxx
Jaxx is a multi-currency Ether, Ether Classic, Dash, DAO, Litecoin, REP, Zcash, Rootstock, Bitcoin wallet and user interface. Jaxx has been designed to deliver a smooth Bitcoin and Ethereum experience. It is available on a variety of platforms and devices (Windows, Linux, Chrome, Firefox, OSX, Android mobile & tablet, iOS mobile & tablet) and connects with websites through Firefox and Chrome extensions. Jaxx allows in wallet conversion between Bitcoin, Ether and DAO tokens via Shapeshift and the import of Ethereum paper wallets. With an array of features and the continual integration of new currencies, Jaxx is an excellent choice for those who require a multi-currency wallet.
Armory
Armory is an open source Bitcoin desktop wallet perfect for experienced users that place emphasis on security. Some of Armory’s features include cold storage, multi-signature transactions, one-time printable backups, multiple wallets interface, GPU-resistant wallet encryption, key importing, key sweeping and more. Although Armory takes a little while to understand and use to it’s full potential, it’s a great option for more tech-savvy bitcoiners looking to keep their funds safe and secure.
Trezor is a hardware Bitcoin wallet that is ideal for storing large amounts of bitcoins. Trezor cannot be infected by malware and never exposes your private keys which make it as safe as holding traditional paper money. Trezor is open source and transparent, with all technical decisions benefiting from wider community consultation. It’s easy to use, has an intuitive interface and is Windows, OS X and Linux friendly. One of the few downsides of the Trezor wallet is that it must be with you to send bitcoins. This, therefore, makes Trezor best for inactive savers, investors or people who want to keep large amounts of Bitcoin highly secure.
Ledger Nano
The Ledger Wallet Nano is a new hierarchical deterministic multisig hardware wallet for bitcoin users that aims to eliminate a number of attack vectors through the use of a second security layer. This tech-heavy description does not mean much to the average consumer, though, which is why I am going to explain it in plain language, describing what makes the Ledger Wallet Nano tick. In terms of hardware, the Ledger Wallet Nano is a compact USB device based on a smart card. It is roughly the size of a small flash drive, measuring 39 x 13 x 4mm (1.53 x 0.51 x 0.16in) and weighing in at just 5.9g.
Pros:
Cons:
Green Address
Green Address is a user-friendly Bitcoin wallet that’s an excellent choice for beginners. Green Address is accessible via desktop, online or mobile with apps available for Chrome, iOS, and Android. Features include multi-signature addresses & two-factor authentications for enhanced security, paper wallet backup, and instant transaction confirmation. A downside is that Green Address is required to approve all payments, so you do not have full control over your spending
Blockchain (dot) info
Blockchain is one of the most popular Bitcoin wallets. Accessing this wallet can be done from any browser or smartphone. Blockchain.info provides two different additional layers. For the browser version, users can enable two-factor authentication, while mobile users can activate a pin code requirement every time the wallet application is opened. Although your wallet will be stored online and all transactions will need to go through the company’s servers, Blockchain.info does not have access to your private keys. Overall, this is a well-established company that is trusted throughout the Bitcoin community and makes for a solid wallet to keep your currency.

Questions and answers from our latest #AskWTC AMA

Q1.

Slack name: bamber
Q1.1: In a retail clothing shop customers often pick up items and return them to the wrong rails. When a member of staff then resets these items the system would log them, skewing the grab rate data. What have WaltonChain done to solve this issue?
Answer: Waltonchain’s solution with its unique RFID-based hardware tracks not only clothes but customer picks. Data from different readers (shelves, fitting rooms, price scanners, checkout counters, etc) is aligned and verifies each other. The sequence of RFID reads are time-aligned for interpretation of user behaviors and interests.
 
Q1.2: Do the RFID clothes rail scanners work on circular rails which are popular in clothing shops?
Answer: Technically, yes. Practically, we are further testing and improving performance for the most popular environments and scenarios in the clothing industry.
 
Q1.3: Items of clothing which are neatly folded and displayed in piles (e.g. jeans) present challenges in terms of placement of RFID scanners. How does the Waltonchain system overcome this?
Answer: Okay, we see where this question is coming from: You are asking this because you have not realized the fundamental difference of the RFID tags we use vs. some of the NFC tags you’ve seen out there. This is a good question. Let me elaborate a little, and take this opportunity to give a basic RFID 101.
For basics, you should just remember that RFID is the process by which items are uniquely identified using radio waves. RFID tags/chips are the hardware chips that in everyday use people usually refer to as “RFID.” This is fine in daily speech.
On a very high level, to make it simple, there are two types of RFID chips we see in the Blockchain world:
  1. Ultra High Frequency (UHF) RFID tags, which operate in 856 MHz to 960 MHz frequency ranges; and
  2. High Frequency (HF) Near-Field Communication or NFC tags, which operate in 13.56 MHz frequency ranges (these tags can be read by your phone. Recently iPhones have implemented this capability.)
Both of these chips are categorized as RFID tags, under the RFID family. The difference in these tags are tldr, but the takeaway for our case is this:
Our Waltonchain-compatible UHF RFID chips are readable 9 feet away, in a batch, all at once. NFC chips are usually used in peer-to-peer, i.e., using your phone to scan an NFC chip in very close proximity (a couple of inches or closer).
If you watched our demo video made by Boxmining on Youtube, you will notice that we use UHF RFID (Ultra High Frequency) technology.
Finally, to answer your question, with UHF RFID system and the Walton RFID reader, we will be able to read with 100% accuracy the tags within a pile of clothes, neatly folded or not.
 
Q1.4: In a clothing shop can staff manually amend the blockchain data? (if activities in the store results in skewed data - e.g., a large number of items being mistakenly moved resulting in artificial grab rate data etc. can anything be done by the staff to correct this?
Answer: Nobody can tamper with data on blockchain. Our specially designed RFID end devices collect data and record on the chain automatically and reliably. At the same time, data analytics can be used to interpret employee behavior as well.

Q2.

Dominique‏ @DomFromParis Nov 18
Q2: Can you confirm it will be 5000 Walton for a masternode and what % will be paid to the holders?
Answer: Yes, holding 5000 WTC qualifies a node to be a Masternode, which will earn extra rewards for every mined block. The percentage and/or reward system will be announced with other details. Please follow our official announcements.
 

Q3.

Sam Lyons‏ @SamTaweets Nov 18
Q3: AskWTC If possible can you please tell us if you have any partners already secured for the RFID when you go live on-chain?
Answer: As you will have seen from our blog posts and various news articles we have several close partners and have signed strategic cooperation agreements with a number of organisations. We released news of one just last week. Many of these companies have already been using our RFID technology and all have projects planned for RFID + Waltonchain integration. In terms of ongoing discussions, we will not release specific information about them until they are 100% confirmed.
 

Q4.

Dominique‏ @DomFromParis Nov 18
Q4: Why Walton does not have a GitHub?
Answer: We will have a GitHub. We will provide the GitHub for our full node, light node, wallet, etc. We want everything to be thoroughly tested before public access. Also, our software rollout has to be aligned with hardware R&D.
 

Q5.

Peter Peterson‏ @Hamster10Peter Nov 18
Q5: Binance is a good exchange but is it manipulated by trading bots to keep the price unnaturally low. When will WTC be listed on Bittrex or Bithumb? We really need one of the biggest exchanges so our beloved coin can grow naturally.
Answer: We have been discussing cooperation with many well-known trading platforms. Please pay attention to our official announcements.
 

Q6.

Sam Taylor‏ @chunkylover199
Q6:What is to stop someone simply removing a tag and leaving the tag on an adjacent item of clothing on the rack in order to steal a piece of clothing?
Answer: We are developing many different ways to integrate the RFID tags into products. We will make it difficult to remove a tag without damaging it, or the host. In the case of clothing, tags do not have to be attached. They can be printed, woven or sewn into the article itself.
 

Q7.

Derek Chow‏ @maseradee Nov 18
Q7: Are there any mechanisms in place to stop someone cutting off the RFID tag from a clothing article and walking out?
Answer: It is difficult to develop a perfect theft deterrent system. The methods currently used by shops can deter a portion of the thefts. Additional developments like sewn-in tags will increase deterrence. Also, our RFID tags are not always able to be cut. Wait and see.
 

Q8.

Rational Riddler
Q8: Will businesses using Waltonchain need to run masternodes or will the unique Waltonchain hardware provide all the mining a business needs? How many readers/scanners will your clients need per store to properly implement the system? #askWTC $WTC
Answer: We aim to provide a fully automated solution with complete software and fully-capable hardware. In doing so, businesses that adopt the Waltonchain system can focus solely on their day-to-day requirements without concerning themselves with those aspects covered by the Waltonchain system. Our entire ecosystem scales up with businesses as child chains are created. We want to make it as easy as possible for our partners’ businesses to fulfill their growth potential.
 

Q9.

wtcrfid‏ @wtcrfid Nov 18
Q9: AskWTC What hardware will I need to run my 5,000 WTC masternode? Will a RasberryPi type system suffice?
Answer: While a RasberryPi could be capable of running a node, It would not be ideal. Please wait for our news on the mining hardware needs.
 

Q10

Sergey‏ @CryptovalleyOF 20 hours ago
Q10: Most of the community is concerned about the relation between the price of a token and the blockchain system, what will a WTC token will be equal to? 1WTC= 1000 Transactions? 1WTC=18,000,000,000,000,000 transactions? I would love to hear your response.
Answer: The transaction exchange rate is established by the marketplace, not by Walton.
 

Q11

Syed M Mujahid‏ @smmujahid
Q11: Walton Chain system essentially include RFID tags, Scanners and blockchain application that will be customizable according to business needs. According to you, tag might cost around 5 cents, what about each scanner and the application. Will it be viable for small businesses
Answer: Our definition of an affordable system is twofold: 1) something that provides long-term additional benefits and 2) something that is worth its cost. The Waltonchain system has been tested in industry and has yielded positive results that our clients did not expect. One example is an increase in distribution efficiency of nearly 100%.
 

Q12

Lemuel Wong‏ @2BitsCrypto
Q12: Will it be possible to use Walton Chain RFID technology in Luxury handbags, such as Hermes for example, to verify it as an authentic item that is recorded in the blockchain? Or can RFID chips be copied/replicated? Last thing are your RFID chips EMP proof? Thank you Walton team!
Answers: Yes, verification of authenticity is a very basic use case. Our RFID chips can not be copied or duplicated. EMP proof RFID chips are not an immediate concern, but are absolutely within the scope of our research and development.
 

Q13.

Sergey‏ @CryptovalleyOF
Q13: One of the main concerns I have about the Waltonchain project is what will happen when the new wallet and blockchain becomes publicly available. I'm sure there will be lots of scams and fake websites claiming to be Waltonchain - what will you do to ensure that the changeover is as safe as possible?
Answer: Security has and always will be among our highest of priorities. This is primary in our system design and deployment but also in ensuring the trust of our community. Official announcements will be made to assist in the transition from ERC20 tokens to official WTC coins.
 

Q14

Errrrr_pesillo‏ @pablo_melo7 Nov 18
Q14: How do you plan to compete with an RFID solution on the IOTA network in future with no mining fees? (Assuming IOTA delivers on their promise) #askWTC #AskWTC
Answer: Our RFID system includes a revolutionary RFID readewriter that not only communicates with tags but also performs the task of mining.
 

Q15

Rami Yousif‏ @ramiyousif91 Nov 18
Q15: Is there any upgrade for your website? #AskWTC
Answer: Yes, there will be an upgrade to our website moving forward. Please watch for our official news release.
 

Q16

matthew collins‏ @mineu999 Nov 18
Q16: Why was there a QR code on the blockchain demo product and will it be there for the final production model? #AskWTC
Answer: Through our network of pioneer users, we are constantly evaluating and refining the production model design. Many aspects may change and many may remain the same. This all depends on feedback from our case-study clients.
 

Q17

Collin‏ @CollinsCustomIP Nov 18 Q17: Please address the wabiico competition & specifically describe how your patents protect your specific (hopefully novel) RFID technology. #askWTC #bitcoin #btc #usecase #blockchain #rfid
Answer: The Waltonchain system starts at an integrated circuit level and will be incorporated directly in the manufacturing of electronic devices and products. At this stage, no human interaction occurs—thus the chain of authenticity begins. We can also integrate our RFID technology at higher levels in the manufacturing/supply chain, such as in packaging, as other competitors might.
Our patents and IC RFID designs incorporate technology not seen in the RFID space before.
 

Q18

Tristan Maunder‏ @WTCTricky Nov 18
Q18: #AskWTC For masternode holders... Are we going to be able to store our WTC on a hardware type wallet for security? "cold staking"
Answer: At this stage we cannot say with 100% certainty that “cold staking” will be implemented. We hope to work with vendors like Ledger and Trezor to implement “cold staking.”

First time using Bitcoin at physical store (my experience)

I was excited to use Bitcoin for my first time at a physical store, only to be embarrassed and in the end I paid for my dinner 4 times. (i've used bitcoin online with no problems many times).
Here is what happened:
1) A food truck advertises they accept Bitcoin 2) I said i'd like to pay with Bitcoin 3) He pulls out his iphone and mentions he hasn't had someone pay with Bitcoin for a while. 4) He tries to find his bitcoin wallet app - I have no idea which wallet he used as I didn't really recognize the symbol (it took him a bit of fumbling before he found it) 5) A bit more fumbling to setup the payment request 6) he figured it out and typed in the price to request: $9 7) The QR code was generated 8) I pressed the QR code symbol on my coinbase wallet and it momentarily froze/glitched my phone but 2nd time worked. I paid with my coinbase wallet by scanning the QR code - it did some weird vibration thing on my phone with absolutely no confirmation that I sent a payment - nothing happened on my wallet or his wallet visually. In the spur of the moment and with a line up behind me I scanned it again..still nothing. He said to try again, so I did and again nothing. 9) He gave me the slip that says I paid and said to get my food cause he has to help the other people behind me now 10) I press return/back on my coinbase wallet while waiting at the side and see that there are 3 pending send payments to him of $9 on my phone and says pending even 1 hr after. For some reason each transation had a decline button but when pressing it a message pops up saying it failed due to not being a request. 11) I get my food but I am now akwardly waiting at the side staring at my phone and the three pending send transactions. After he helped everyone in the line I went up to him and he said he still got nothing and went to look into the transaction history and shows the last transaction someone made with him was June 12th. During this conversation he says he's no bitcoin expert and that he lost money by accepting bitcoin because he never cashed them when they were worth "double" in 2013. 11) ended up paying with my mastercard :/ 12) I logged into my coinbase account on my laptop maybe 2 hours later and see all payments have been sent to him with 8 confirmations (no longer pending)
This experience ticked me off and when I got the food I had to tell my mom, brother and his fiance that it didn't work and that I may have paid him 4 different times (now confirmed after looking at my coinbase accnt)
EDIT: Thanks everyone!, yeah i can't f igure out if it was coinbase or his wallet that caused the problem (or maybe both?). I never had problem with coinbase hot wallet for spending online before. (maybe that was because they were using coinbase as the processor online). I'll try my mycelium wallet next time. I guess we can say my first experiment went bad ;) But hoping the next one will be better after learning some things myself from this experience (like NEVER scan a QR code more than once even if you dont think it worked and ill try myecelium next time).
P.S: This post isn't meant to hound bitcoin - I love bitcoin with a passion. Just wanted to post my first experience using bitcoin at a physical store and how I felt about it. I def learned a few things on my side.

The speed of bitcoin network propagation is awesome....

I just sent the equivalent of 50 USD to Wikileaks from an android wallet I created to experiment with mobile payments (I dumped my iPhone just to buy a phone that would support a native bitcoin wallet incidentally... totally worth it)
https://blockchain.info/address/1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v
And this is what amazed me... I scanned the QR code on the site and punched in a figure and hit submit. And it took about 3-4 seconds for the phone to register the transfer... and then the blockchain website above updated in REAL TIME.
THREE SECONDS??? For a basically anonymous wallet to send fifty bucks to Wikileaks? Screw 1200 USD. Bitcoin is priceless. The more I use it the more I feel like I'm living in the future.

BIP 38 invalid passphrase, need tips! Can't sweep bitcoin

EDIT 2: SOLVED! Guys I solved it when trying different combinations. So happy! Thank you to all that offered help and took time out of their day! Hi!
Long time lurker here who just made an account for this post. I have been trying to sweep a BIP 38 paper wallet that I have created using bitaddress.org however I get the message invalid passphrase. I have the passphrase written down and the private key on a printed card. I tried scanning the qr code with mycellium and other apps but it does not seem possible to scan BIP 38 codes on iphone so instead I typed the adress into blockchain.info. Blockhain askes for the passphrase but when I type it in I get the invalid message. Now I realize that it is my own fault if I somehow wrote down the wrong passphrase when I created the wallet and that my money might be lost forever. I just wanted some tips if you guys have had similar problems and were able to solve them. Any help would be appreciated since I have half my bitcoin on this wallet. If you need any more info please feel free to ask. Also I'm sorry if my grammar is poor, English is not my first language.
Thanks!
EDIT: I am a very careful person when dealing with sensitive info so it is safe to say that I checked the private key and passphrase multiple times when creating and writing them down. Though I am not sure that I checked that it was valid afterwards on bitaddress (stupid I know) but I did not know you could do that at the time.
Also I don't know if it is worth noting but I did print the wallet using a service that seems like they are no longer in business called iirc crypto-cards.com. They were a canadian website I think, maybe something happened to the private key when they made it which is now screwing with me? Anyway they have not stolen the money since I can still see it using the public key. This was around 3 years ago but I made a card before with them that I later sweepd. I had one problem back then with an invalid passphrase but that was because I did not put in the spaces between the words. For this one I have tried with and without spaces and alot of other combinations.

MyEtherWallet now Supports Sending Any Ethereum Token (ERC-20) — also learn about our future plans

Sending Tokens

We at MyEtherWallet just added the single most requested features: Sending any Ethereum token on the network via a super simple GUI. This is now live on MyEtherWallet. Any token that is built on the ERC-20 spec is now supported and — yes — you can add your own super special token.
By default (meaning you don’t have to do anything besides click a single radio button) we currently support viewing the balance and sending of:
Sending Token Interface:
https://ipfs.pics/ipfs/QmVkVDGxgesf299gQhXp9kFxVcH8EkEgu81p5T2faenok7
https://ipfs.pics/ipfs/QmXgMsaQrPdjxhJdV5EKCC7PkWxRsh48vw2fk4w7rPGDM9
But, by clicking the “Custom” radio button, you have the ability to add any custom token on the network by inputting the Address of the token, the Token Symbol (what you want it to be referred to as), and the number of decimals. If you have ever added a Watch Token to Mist, these items will be familiar to you.
Adding a Custom Token: https://ipfs.pics/ipfs/QmTRSvUwfzTfzmP6U1iaE82ZWCBWfzuSk8UQfA1gKzAxa1
The real magic happens once you add this custom token. Like Mist, you can now send it to any address and you can also view the balance of the token in the sidebar. However, unlike everything else on MyEtherWallet, the address of the token, token symbol, and decimals will be saved in you local.storage and remain there when you return to MyEtherWallet later. That way, you don’t have to re-add tokens each time.
Custom Token Added: https://ipfs.pics/ipfs/QmZTJauzVLXWWFkZ1mYqvbKrxR8E2KQzeamBbKb8B6Y7VV
We plan on supporting DGX and DAI and REP when they are ready. We are open to adding any other commonly used token as a default so that you don’t have to track down the address / decimals. Just shoot us an email, comment here, or reach out to us on twitter and let us know what tokens you use most.

Misc

We rearranged and re-named the navigation to make it clearer and more simple. Now you will only Withdraw DAO using the old DAO tab and claim DGD at the old Digix tab. All token transactions will occur on the Send Tokens page.
You can also now view all your token balances on the Send Tokens tab and View Wallet Info tab.

The Future

As some of you know, kvhnuke and I are in Switzerland right now partying it up. And by partying, I mean coding our brains out with some amazing people here. We have re-examined our goals and the future of MyEtherWallet and come up with the following list of items we want to accomplish.
Short Term
Medium/Long Term

Ethereum Classic

Will update status shortly and will post separately so the discussion can stay focused on Tokens and The Future in this thread. Please yell at us on the other thread. Thank you. Edit: Posted ETC update here
PS: As always, let us know if you encounter any issues or recommendations on how we can improve. Thank you for your support.
PSS: If you are into steemit or whatever, my lovely fiance posted this there so you can upvote/contribute to our pile o' riches or whatever happens on steemit 😉

Help us create the best mobile wallet – join Billion test-net beta! [iOS]

Hey there, folks!
We are a team of cryptocurrency enthusiasts behind Billion Wallet (screenshot) for iOS. It's common among developers to think about their project in a special way, and we are not an exception – we do feel like we created something different. We believe we have a reason to think like that, and we invite you to participate in a public beta test that allows you to play with all features without spending real bitcoins ㋛.
We value Bitcoin Cash very much, but due to roadmap inertia we still do not have a version that works natively with Bitcoin Cash – we are sorry for that. What makes us very sad, is that our posts on Bitcoin are always deleted for no apparent reason and without any explanation. It's not a kind of treatment we expect – we work hard for the benefit of the Bitcoin infrastructure, we are a very small, self-funded team of cryptocurrency enthusiasts and the ability to participate in open communities is vital to us. We hope you do not mind we invite you to test the wallet that works in a test-net Bitcoin Core chain.
Here is what's unique about Billion:

Private

Not only Billion never asks you to enter email or phone number, but it also implements a unique feature called Reusable Payment Codes. Payment Code is a special kind of address that can be freely published online and no one will be able to calculate the amount received. Kind of Monero Stealth Addresses but in a Bitcoin world! You can read a high-level overview of this technology on our Medium blog (a 10-min read). Billion is an SPV wallet that does not depend on a central server for any critical functionality.

User-Friendly

To make cryptocurrencies easy to use for everyone we have developed an entirely new visual paradigm. If you ever experienced struggle while using a crypto wallet, we encourage you to try Billion – that's something new on the market. You can read a brief explanation of Billion user-interface on Medium (4-min read), or watch a 30 seconds-long promo video. Please forgive us the part of the video with 10$ fees :)

Social

One of the most important aspects of Billion is a system of contacts based on Payment Codes. Once you have added your friend to a list – either using Air Connectivity (Bluetooth connection) or by importing/scanning a Billion Card – you can make payments without any copying/pasting/scanning. This way, a payment workflow is simplified drastically, and the privacy is not sacrificed at all. Moreover, such a system is cross-platform: you can add contacts from other wallets that support Payment Codes. As of now, Samurai (BTC-only) and Stash (BTC + BCH)) on Android are two wallets that support Payment Codes (and Stash can be used on TestNet). And by the way, Stash Wallet works great in test-net so you can experience the magic of cross-platform Bitcoin contacts right away!

How to Participate

  1. Download Billion TESTNET Edition from the App Store
  2. Create a new wallet. Once it's synced, tap onto the balance tab to display your Billion card. Assign a pseudonym and avatar to make it more recognizable.
  3. Share your BillionCard picture in comments, or join a dedicated Telegram channel. We will send you some test-bitcoins so you won't need to use any faucets!
  4. Add BillionCards of other users who participate in beta testing to your list of contacts (tap onto 'Contacts' icon -> 'Add contact' -> 'Scan BillionCard' -> 'Extract QR-code from picture' and choose the image you saved to media library). Send them some coins, and tell us how do you enjoy the workflow.
  5. If you have friends with whom you can test Billion irl, we urge you to test Air Connectivity and Billion Requests.
Thanks for reading and let's create the best mobile cryptocurrency wallet together!

P.S.

We have to polish the version on a single platform with one cryptocurrency first, and we need your help. We are looking forward to testing Billion with you!

Is there a way to use a ledger nano S with a bitcoin ATM?

To use a bitcoin ATM, I need to scan a QR code to be able to deposit into my ledger wallet.
I have an iPhone - how do I get the QR code for my wallet onto my iphone so I can scan it to make the deposit?
Or do I need to run the wallet chrome app on my desktop, then take a picture of it with my smartphone?
Surely there is a better way..?

Jaxx Ether / Bitcoin wallet to undergo intensive security audit over the next 2 weeks. Version 1.0 to be released upon completion.

Anthony from Jaxx here. Next week, security auditors Sergio Lerner and Juliano Rizzo at Coinspect will be starting an intensive audit of our Jaxx code. We believe this audit is a necessity, and only after his team gives the go-ahead will we take Jaxx out of beta and officially release the 1.0 versions across all platforms.
The feedback from the community has been extremely valuable in fixing bugs and adding new features. We understand this is a need for a user-friendly wallet that can be trusted and relied on for everyday use and it is our goal to make that happen with Jaxx as soon as possible. Rightly so, Jaxx has been in beta up to this point and will remain in that state until we feel 100% confident our code is rock-solid. Until 1.0 is released, please give Jaxx a spin, but only use amounts you'd be willing to lose.
Among other things, the following will be included in the audit.
Please note each point here is broken down into several subcategories, but I'm only listing the high-level headings here.
The audit is expected to take 10 days. Please email me at [email protected] or call me at +1 416-831-9593 if you have any questions about the audit, or want to know anything else about Jaxx.
About Jaxx:
Jaxx Bitcoin & Ethereum Wallet by Kryptokit Philosophy:
With a focus on unifying the look and feel across multiple devices and platforms (currently 9) and focusing on customer service, security, design, and user experience, our goal is to make the Jaxx Bitcoin and Ethereum wallet default wallet of choice for the masses.
