Copay Wallet Review - Multisig Bitcoin Wallet -Top 10 Best ...

The place for everything bitcoin!

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no one in charge of bitcoin and it is made up of willing participants. Bitcoin gives you the option to be your own bank.

PSA: Bitcoin.com's Wallet new releases do not currently have any publicly available source-code. Be very careful; do not trust them with funds you care about without this transparency

TL;DR: Bitcoin.com used to publicly release and track changes of their wallet's source code. Currently it is NOT true anymore for the most recent versions (5.x/6.x). Please be careful, trusting a closed-source/non-public source wallet is VERY risky for your funds.
This wallet is mainly an altcoin focused wallet nowadays, it has multiple other flaws and serious unresolved security issues.
But since it is still possible to store actual Bitcoin funds on it and it appears in the first results of a search for Bitcoin wallets (due to its name) on various App stores I've figured this post could be useful to new/unaware users.
This wallet is supposedly (hard to tell without source code) still a fork of Bitpay's CoPay wallet which is under MIT License. If this is the case authors have no obligation to publicly release the source code, but up until the last couple versions it was public and tracked on this GitHub repository.
Without any justification the new releases are now happening on a new GitHub belonging to apparently "bitcoin.jp", without any tracked source code in the repository and with only binaries available for download.
There are compressed files named "Source code" along the releases, which are empty (only containing a meaningless README file in them). Those files could easily be there to deceive people into thinking everything is like before and that the source code is still available but it clearly is not the case.
You should never use a close source wallet as it generally implies that nobody was able to independently review and audit it. Without this ability, you have no guarantee that this application is not going to leak and/or purposefully steal your private keys/seed/funds. When a wallet goes from a public open-source model to a closed source/non-public source like this wallet it is even more suspicious.
I've seen Roger Ver being asked about it multiple times on btc and he only directed users to the new GitHub, without further comments when people pointed out there was no source code there.
So please, be careful, and do NOT blindly trust this company with your funds. There are plenty of wallets that are actually open-source (with publicly available source code).

Is Hodl Wallet safe?

I recently made a post on the beginner sub and mentioned I was using this wallet and someone replied saying: “Why on earth you are using a wallet which does not even have any traffic on it, I am not sure if you were advised to do so, but please use some wallet which keeps your cryptos safe. After all its your hard earned money.”
I’m a total noob and only have about $100 in BTC right now and was keeping it on Coinbase. But after reading stuff here I thought I was seeing a lot of good things about this wallet so I got it and sent my satoshis there. I eventually want to get a Trezor but not until I have enough bitcoin to justify buying it. Will I be ok using Hodl Wallet for now?
Thanks!

Fork Bitcoin.com wallet for BSV

Would anyone be interested in a clone/fork of the Bitcoin.com wallet for BSV? Back before the split it used to be a nice simple phone wallet that could be used to introduce noobs too. I feel the other BSV phone wallets are no good as they're closed source. Obviously you should never trust a closed source wallet as it could steal your money.

The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here.

What's the best BCC android wallet?

I researched a bit on the wiki and online, and found the Bitcoin.com and Electron Cash wallets to be the most popular. I've downloaded and used the Electron Cash one, but on android the camera on electron cash doesn't work(for scanning QR).
Are there any other mobile wallets which you guys recommend in which the camera works?
Thanks for the help!

How to get BTC out of CoPay wallet

I freely admit I know pretty much nothing about BTC. I make about one purchase per year using it, and each time I have to re-teach myself how to go about it. My ineptitude and noob status caused me to get banned from Coinbase last year, so I'm a little gun-shy about doing something stupid again.
I have a CoPay wallet that I've had a couple of years. Already had a tiny amount in there, and as I was ready to buy something again today, I transferred some more money from my exchange account into CoPay. Went to go pay the invoice and CoPay will not accept the recipient - it shows up in red with an X next to the name, and I can't progress from there to send the payment. After researching, I heard something about SegWit and CoPay and incompatibilities. I really don't know anything about SegWit, but after much frustration, I finally decided I'd try a different wallet app with better reviews. Went to transfer BTC from CoPay to the new wallet, and.... OF COURSE CoPay won't accept the new wallet address either.
I'm beyond frustrated. I just want to pay the invoice and be done with it. Every time I do this, it ends up being a day-long ordeal. Can anyone help an old lady out? I'm usually tech-savvy but Bitcoin really escapes me. I'm ready to start drinking in the afternoon after this...
TIA

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.

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.

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.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

An in-depth overview of different mobile wallets

Disclaimer: A lot of time went into writing this and more research than I anticipated. Errors are not just possible, they are certain. If you find any mistakes, please reach out to me and I'll edit. Furthermore I know I probably missed a couple apps, there are a lot out there. If I missed a big one, then again contact me and I'll consider adding it. If you are reading this in the future, note that these apps update regularly, anything mentioned here may have changed by the time you are reading it.

What is a mobile wallet?

A mobile Bitcoin wallet is an application for a mobile device which acts as a lightweight wallet and allows you to store, send and receive Bitcoin (or other cryptocurrencies and tokens). Mobile wallets use SPV (Simplified Payment Verification) to allow wallet functionality without having to download the whole blockchain. This is very important as barely any mobile phones have enough storage space required for the full blockchain. Mobile wallets are also considered hotwallets, meaning they have an active connection to the internet. The mere fact of being 'online' allows for a number of attack vectors and as such should never be used to store large amounts. It is however not unsafe per se. Private keys are stored locally and encrypted. Some wallets keep backups of those encrypted private keys on a server of their own, and this is something to take note of, but not to fear. So without further ado, lets get to it. I focused on Android wallets, but many of the wallets mentioned here have iOS versions.

Coinomi No No 18 word seed A ton Custom No Advanced
Mycelium No No 12 word seed No Scrollwheel Tor Optional Intermediate

Wallet Breakdown

Samourai

Samourai focusses heavily on anonymity and obfuscation. Addresses are never used more than once. When making a transaction there is an obfuscation slider. Samourai has had SegWit enabled since October. Furthermore it offers a plethora of different features, too much to sum up here. If you are an advanced crypto-user you should definitely check out this wallet and their website which explains all of the different features. The UI takes a bit of getting used to though.

Breadwallet

Breadwallet is a very simple to use, straightforward app. The UI is slick and intuitive and in-app support to basic questions is very well incorporated. This could be a good wallet for a new person to the scene. The lack of advanced features will make this app not the go-to for more experienced users. It does however feature fingerprint authentication, which is cool, as well as BCH extraction. The lack of SegWit and complete absence of custom fee's is a problem though, especially since fees have gone up during the recent BTC spike. With only 2 fee options to choose from I simply can not recommend this wallet to people who are looking to make frequent transactions.

GreenAddress

When I first started with Greenaddress I didn't like the UI, I found it a bit clumsy. So definitely not user-friendly for a beginner. On the plus side it allows a choice of 2FA settings. Furthermore it has SegWit enabled and it has some advanced features like nLockTime transactions and it offers a service for instant transactions. This all feels very Lightning Network-y, which makes sense as GreenAddress is a part of Blockstream. Our friends in the other sub will most likely have something to say about this. I'll refrain from this and just say the following: this is an advanced wallet with promising features. If they clean up their UI a bit I could see myself using this without hesitation. The fact that they have MultiSig is a big plus as most mobile wallets do not have this functionality.

AirBitz

Unlike any other wallet I fired up at that point, this app did not prompt me with a 12- or 24-word seed. Instead it made me make an account, the regular username/password combo. After some research I found that these are not stored in a local database on their end. Which means that recovering your password in case of loss like with every other username/password login method we are so used to, is not possible. It is merely a different representation of an encryption key, allowing you access to your private keys. It features some interesting stuff though, NFC-compliant transactions and Bluetooth Low Energy (BLE) for example. Clearly this app is meant to be a bridge between users and merchants and has focus on making regular in-person transactions. Thus it mimics some non-crypto related payment apps that we have. Personally, I am not a fan, but I can appreciate the design philosophy and I would't be surprised if their design model worked very well in the future with the LN or with other crypto's that focus on small payments. As for the UI, it's fairly simple, yet horribly cluttered with partnered services. Good for non-techies maybe, but not for more experienced crypto-enthusiasts.

Electrum

Much like the desktop wallet I used years ago when I first started with Bitcoin, the mobile wallet is minimal. Straightforward and without fancy colors or UI. For those of us who have known the internet before Facebook, this app will feel strangely familiar. This is a classic example of a no-nonsense wallet with the features that really matter. SegWit and MultiSig enabled. A further lack of advanced options might be a turn-off for some users out there though. I did however find the option to spend coins from unconfirmed transactions. This could be very useful in case you want to cancel out a previously stuck or erroneous transaction and ensure it's never cleared. One downside to this wallet is the very primitive way of setting a custom fee. No guidelines, scrollwheel or info. Just a simple box in which to put your fee which won't help intermediate users, only experienced users.
Edit: sidenote on the SegWit implementation by Electrum http://www.crypto-economy.net/electrum-3-0-enables-bech32-segwit-addresses/?lang=en

CoPay

Of all the apps I've tried up to this point, CoPay had the best initializing phase, succinctly explaining risk and security. I can not imagine a better intro to a wallet for a first time bitcoiner. It being of a product of BitPay, of which I am personally not a fan, I have to admit though. This app looks clean, feels fast and is easy to use. It successfully demystified MultiSig functionality in its UI and partnered services are not obtrusive in the design. Downsides are lack of fee setting possibilities and SegWit. The latter I really do not understand given their main core of business. If it wasn't for those last two points, I would not see why not to recommend this wallet.

ArcBit

This app dissapointed me a bit. It starts out of the box, not mentioning any backup seeds or tutorial on the wallet itself or Bitcoin. It has no SegWit, no MultiSig, a lack of features and whilst a backup seed can still be requested from the settings, I feel it is of the utmost importance that such a security measure is not quickly overlooked. The lack of fee management tops it off. While this wallet works just fine and looks just fine, there are too many alternatives out there with better options and functionality for me to ever advise anyone to use this wallet.

CoinSpace

CoinSpace is one of those apps that could be really cool, but completely missed the boat on some other design choices. In-app ads unless you pay 1.6$ or something. Settings hidden behind a CoinSpace login screen. It features multiple tokens though with built in conversion through ShapeShift, which could have been awesome. But the excessive ads are just a big no-no. Lack of SegWit and limited fee options make this one of the least interesting wallets out there.

Simple Bitcoin Wallet

Simple Bitcoin is a very basic, barebone wallet. Feels like a one-man project. Almost no settings possible at all. There's much better out there.

Bither

I oddly liked Bither because of its design that reminded me of websites from the 2005-ish era using lots of gradients. Its one of those apps that you either like or you don't. The UI is not bad, but could be better, there's some functionality hidden in the settings, but not enough to satisfy. One very useful feature is built in BCH and BCG extraction. This is the first app I encountered with built in Bitcoin Gold access. It also has a separate tab with just market price information, which is really useful for the price ticker addicts among us. Furthermore it features Cold/Hot Storage View which allows you to monitor cold storage and with a nice graph shows you the distribution between Hot and Cold. Cool stuff. I would suggest to check it out, I'm sure some people will like and some won't. Do note, no SegWit. I would personally use this as a view-wallet only. Not as a spending wallet.

GreenBits

GreenBits is like the light version of GreenAddress. I tried looking for why one team would make 2 wallets but could not find a definitive answer asides from GreenBits being Android-native. And while some resources state MultiSig functionality and Tor through Orbot, I couldn't find those in this app. It does however sport SegWit and custom fees like GreenAddress. On the UI front I feel much more comfortable with this app though and I could see it being better received by average users. Looks like a good spending wallet without much extra.

Jaxx

Jaxx is a rather large wallet that supports many many many different coins with built in ShapeShift functionality. It did suffer from a hack earlier this year which is why this wallet has been discredited. I would however suggest looking into this one if you are invested in multiple different coins and regularly swap between them to get some financial edge. Lack of SegWit and fee options don't make this an ideal app for Bitcoin-only users.

Xapo

Xapo, known for its cold storage solutions was one of the apps I was eager to check out. Upon starting I however first had to verify through a text message, giving up my phone number, after which I was greeted by a 'Continue with Facebook or email' - screen. Upon choosing email, I was further asked to give up personal information. Nothing personal against these types of business models, but this is not what I am looking for in a mobile wallet. Centralization of personal information is quite in contrast with the decentralized and pseudonymous qualities of cryptocurrencies. This being the 13th wallet I've fired up tonight, I decided to give this one a pass.

Coinomi

Coinomi is very similar to Jaxx in the way that it supports a crapload of different currencies and in-app conversions between different tokens through ShapeShift and additionally Changelly. It does look quite a bit more straightforward though. A good alternative to Jaxx for those multicrypto traders among us. Unfortunately yet again not the best for straight Bitcoiners due to lack of SegWit. It has custom fees though, but much like Electrum, there's no real help here and it's just a manual input.

Mycelium

Mycelium has been my wallet app for a couple years now. Unfortunately the delay in SegWit adoption has me looking elsewhere and in succession writing this article. I really liked the recent addition of the fee scrollwheel, which is still the most detailed and succesful implementation of custom fees in any app I've seen. Having tried out many other apps at this point I can now see Mycelium, while not particulary user-unfriendly, could still very much improve its UI. It is however not a bad wallet, never crashed on me, always ran smooth through multiple updates. But let's not get sentimental here, it's a solid app, but its time for me and maybe you as well to try out something different ;-)

Conclusion

In this excruciatingly long article I've ran through a couple different wallet apps. One thing to learn is that not a single one of these is perfect and there's still room for improvement on many fronts. Which wallet holds your preference today depends largely on what you are looking for in a wallet. Do you want the cheapest transactions, then go for one of the SegWit enabled wallets. Do you like cool functionality, then check out Bither. Is anonymity of a concern to you then Samourai looks like the clear winner. More into multiple coins at once, then Coinomi or Jaxx is the way to go. And this is mobile wallets only, you have your desktop wallets, hardware wallets, cold storage solutions, paper wallets. But I'm all out of ink tonight!
I can't give you specific advice. In this world of cryptocurrencies we are in control of our own money. Being in control of your own money means being responsible for its security too. So make your own decision and due diligence.
Edit: Thanks everyone for the awesome responses. I've had some requests to further mention some important information regarding the wallets. I will write these down here as a memo to myself in the future, at which point I will review the state of mobile apps in greater detail once again. - Open Source or not - iOS version or not - Adding iOS only wallet apps

BitPay App should be the de facto wallet suggestion for new users

We have new users coming to bitcoin all the time - users who are not yet technically savvy with bitcoin but want to have somewhere secure to store some coins.
I see a plethora of suggestions for wallets ranging from Mycelium, Electrum, Coinbase, Jaxx etc, but BitPay is the clear winner when someone new asks what they should use for their first coins:
1) You control your own funds
2) It gets the basic, important functionality right
3) It has a very simple and clean UI
4) It is available on all platforms
5) It is open source
6) BitPay are one of the earliest bitcoin companies, and have an excellent development team supporting the wallet

Dash is not affected by the BitPay Copay attack

Good day everyone !
You might have seen the news on GitHub, Twitter, ZDNet, and various other places on the net. The whole JavaScript ecosystem discovered an attack targeting BitPay's Copay product.In order to be sure the compromised package was included in Copay during the building phase, the attacker had to spread an ingenious, obfuscated and malicious code across the whole ecosystem.This malicious code was looking for a description of a package (bunch of code that works as libraries to enhance programmer's productivity) that had the specific message, "A Secure Bitcoin Wallet", and used that as a decryption key to unveil and execute the dormant code.
This matched two projects: Copay, and our first fork of copay created 2 years ago while Dash was studying the idea of using Copay as a foundation for DashPay. We did not pursue this idea further, and that project was never used.
The Dash Copay Beta that we worked on and released was not targeted and therefore won't manage to steal your funds.

Here is the exact naming thing that got everyone (including ZDNet at one point) confused:
- dash-copay is the name of the repository for the Dash version of Copay, this one is not at risk for different reason (pkg description, different dependencies,...)- copay-dash: Is the library that was also at risk, because it was a fork that we did not even bother to Dashify, so raw, that's it's more a tag of a specific version of Copay that a fork. This one, no one has used (except for bots and researchers that downloaded it in recent days).

So, what happened ?
I’ve been looking at it, thanks to a message from Bitpay.
I want to first say how grateful I am to BitPay; they were blazing fast in sharing with us this information, which allowed us to get in touch with ZDNet and clear all suspicions on Dash.

And secondly for all the foundations they paved, theses packages remain open-source which means that if you do not maintain them, they get outdated, with issues and vulnerabilities. And in this case, I think that the Bitcoin community would benefit from grouping together and starting a Patreon (or forking our governance system) to fund some devs to be able to keep everything up-to-date, to be able to verify the dependencies, and to be able to improve and reduce their dependencies.

So that should be cleared up: This attack targeted everyone, people from React, Vue, Nodemon, from the Node Security team or the Google Security team, experts in their domain also didn't notice it, because it’s finding a needle in a haystack.So clearly, it's not about BitPay, but it’s good warning for all of us to improve our package dependency strategy and review processes.

On the 20th of November, a CS Student found that a package included some strange code. He found a code that he couldn’t really understand, but that is known by most of the crypto community devs (JS).He immediately understood that it was malicious, but it took the community time to get the information, and given the control that the attacker had, we are lucky he didn’t or couldn’t remove the GitHub issue...No fault on that--as a Student, did you know who to contact when you found malicious JS code? (FYI to all CS students: https://nodejs.org/en/security/ is also to be used for third-party vulnerabilities)

This code, present in a minified file, but not in the regular file (the one people actually read), was trying to decipher an aes256 ciphered message that was first turned into a hexadecimal string. The decryption key is the npm_package_description, all packages have one, but Copay specifically has "A Secure Bitcoin Wallet". How did they find that? Well, by iterating all packages descriptions available (and there are a lot of them).

When you enter this passphrase, you then get the code that is injected. This injection as explained before, targets your private keys, requires another package to do that (bitcore-wallet-client), and will then send that information to either:
- A domain bought using crypto and a throwaway email address: copayapi.host (cost: 0.99$/yr..)- If it doesn’t resolve, to a direct static ip (111.90.151.134) which resolves to a Malaysian Transit Service.

Because Dash Copay does not use `bitcore-wallet-client`, and doesn’t have the same description, we were not targeted. The attacker has targeted Bitpay Copay implementation having bch / btc. They didn’t care at all about trying to target other implementations like Dash.

This is a good reminder for us that our decision to limit our dependencies is the right one. It doesn’t help our productivity, but it will benefit the security of our Javascript libraries.

So in the end, this attack specifically targeted the BitPay Copay App from 5.0.2 to 5.1.0.

What they really don't wan't you to know about Dash!

Dash is breaking away with regards to integrations, partnerships and developments that advocates of other Crypto Currencies have become frightened of Dash's future dominance. Unfortunately for most of these other Crypto Currency projects Dash as a platform is well and truly in the driving seat on so many levels.
Lets take a look at some of the achievements in 2017 and upcoming events:

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin ?BTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (?L) or micrometre (?m)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits
For more information check out the Bitcoin units wiki.
