What is a Cryptocurrency Wallet?
What is a Cryptocurrency Wallet? Use this straightforward guide to learn what a cryptocurrency wallet is, how they work and discover which ones are the best on the market. 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.
Desktop: wallets are downloaded and installed on a PC or laptop. They are only accessible from the single computer in which they are downloaded. Desktop wallets offer one of the highest levels of security however if your computer is hacked or gets a virus there is the possibility that you may lose all your funds.
Online: wallets run on the cloud and are accessible from any computing device in any location. While they are more convenient to access, online wallets store your private keys online and are controlled by a third party which makes them more vulnerable to hacking attacks and theft.
Mobile: wallets run on an app on your phone and are useful because they can be used anywhere including retail stores. Mobile wallets are usually much smaller and simpler than desktop wallets because of the limited space available on a mobile.
Hardware: wallets differ from software wallets in that they store a user’s private keys on a hardware device like a USB. Although hardware wallets make transactions online, they are stored offline which delivers increased security. Hardware wallets can be compatible with several web interfaces and can support different currencies; it just depends on which one you decide to use. What’s more, making a transaction is easy. Users simply plug in their device to any internet-enabled computer or device, enter a pin, send currency and confirm. Hardware wallets make it possible to easily transact while also keeping your money offline and away from danger.
Paper: wallets are easy to use and provide a very high level of security. While the term paper wallet can simply refer to a physical copy or printout of your public and private keys, it can also refer to a piece of software that is used to securely generate a pair of keys which are then printed. Using a paper wallet is relatively straightforward. Transferring Bitcoin or any other currency to your paper wallet is accomplished by the transfer of funds from your software wallet to the public address shown on your paper wallet. Alternatively, if you want to withdraw or spend currency, all you need to do is transfer funds from your paper wallet to your software wallet. This process, often referred to as ‘sweeping,’ can either be done manually by entering your private keys or by scanning the QR code on the paper wallet.
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!
Backup your wallet. Store only small amounts of currency for everyday use online, on your computer or mobile, keeping the vast majority of your funds in a high security environment. Cold or offline storage options for backup like Ledger Nano or paper or USB will protect you against computer failures and allow you to recover your wallet should it be lost or stolen. It will not, however, protect you against eager hackers. The reality is, if you choose to use an online wallet there are inherent risks that can’t always be protected against.
Update software. Keep your software up to date so that you have the latest security enhancements available. You should regularly update not only your wallet software but also the software on your computer or mobile.
Add extra security layers. The more layers of security, the better. Setting long and complex passwords and ensuring any withdrawal of funds requires a password is a start. Use wallets that have a good reputation and provide extra security layers like two-factor authentication and additional pin code requirements every time a wallet application gets opened. You may also want to consider a wallet that offers multisig transactions like Armory or Copay. A multisig or multi-signature wallet requires the permission of another user or users before a transaction can be made. Multi-currency or single use?
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.
Do you need a wallet for everyday purchases or just buying and holding digital currency for an investment?
Do you plan to use several currencies or one single currency?
Do you require access to your digital wallet from anywhere or only from home?
Take some time to assess your requirements and then choose the most suitable wallet for you.

Are BTC Wallets Like BreadWallet and Mycelium more secure than Coinbase and Xapo?
I know you have your private keys with you with Breadwallet and Mycelium but how does that protect you in a more significant way? My understanding of Xapo and Coinbase is that most customer funds are in cold storage in secure locations. I like that. Breadwallet states "breadwallet is the only iPhone wallet which connects directly to the bitcoin network. This means that there are no servers to get hacked or go down - your funds are always safe." WTF does that mean? I really don't understand and I've been paying mild attention to BTC since April 2013 from an episode of Econtalk. I bought a little BTC back then but put it in a BTC betting site that didn't last long. I accepted the risk at that time. I finally got back into it with the talk about the Xapo debit card but got Shift cause I'm in the U.S. I'm not an expert by any means but I understand for the most part how BTC works and I still don't get what it means. I like coinbase a lot and I like that I have the debit card connected to it in case I need to spend it quickly. I just don't want to be worried about them. Hardware wallets and cold storage just seem inconvenient. And what if I lose the paper or hw/wallet. Doesn't seem more practical.

''' Ahahaha, dude you're pathetic. You're using your secondary account to make it seem as if your opinion is more popular. Look, its an operating system, simmer down and take your pills.
I got curious when OP wrote bitcoin.org is recommending an offline iPhone. That does not seem to be the case right now.
You mean what you wrote, because your newest comment before this one was before 8 months ago. Suddenly you managed to make a comment after 8 months. Good one.
That being said, your recommendation seems to be questionable at best under that perspective, as your recommended wallet uses Centralized Validation.
Then use bread wallet or [link]1 .
I agree with OP. You should not try to sell your own preferences as superior. It's obvious you got triggered by the "iPhone". There are good and bad androids. An iPhone is an iPhone.
Take a load of this guy, agreeing with himself. I wasn't "TRIGGERED" by your comment but astonished on how you responded when I mentioned the word "Android". You wrote a book on how wrong I was and how stupid I am for giving an advice. And then you follow it by "AND DONT RECOMMEND ANDROID, KNOW YOUR AUDIENCE, oh and I uhh...don't like...apple." Sure you don't. By the way, since you deleted your comment, here it is back up again with me answering your comment:
Oh, so you installed and compiled it from source? Ah my bad. I thought everyone was following their download instructions. (/s) A lot of good, open source projects distributed malware like that.
Yeah, you can do that. Now you're spouting nonsense by saying mycelium which is adviced by bitcoin.org has malware in it. Also, can I have any sources on your claims about "A lot of good, open source projects" Distributing malware by being opensource? You say your job is OPSec, yet somehow that shit sounds so fucking stupid. Go onto /security or /netsec and tell them that. Lets see how they'll treat you.
Sorry, but I will not get lost in this advocacy war with you. My point is way more general that protecting your choices emotionally. You read "iPhone" you got triggered, get the fuck off.
What advocacy ? You started this entire dramatic answer. You're using secondary accounts pretending to be other people, telling me to fuck off, what is wrong with you? Its just an operating system, why are you so damn upset over this?
I will stand by my ad hominem. You must be insane or stupid to recommend an average redditor to modify and replace their android operating system, just so they could use a better wallet.
You do realize that LineageOS is just a fork of AOSP, right? Its not another operating system. And its very easy to do that. You unlock your os, replace the bootloader with TWRP, replace the operating system with LOS, and install an app. There are tools that do this for you (except for installing the app).
Your idea is just so crazy and insane. An operating system has far more attack vectors. Far more problems. Far more devices to support.
Uh iOS is an operating system too.... And apparently encryption, and security updates don't matter when it comes to using an operating system. Not only that but trusting your system apparently doesn't matter as well. Also what attack vectors are there when you've removed the baseband antennas ? Someone breaking into your home and stealing your phone? Because then you have much bigger issues and you should probably buy a cold wallet.
Did you read their code? "Open source" is not a magic word. I read every line of code in breadwallet. I keep track with their few commits. I don't care if their is a "breadwallet" for Android. I use it on an iPhone that is not connected to the internet and has no modifications from factory settings.
Sure you do. And if you do, people like you do review popular projects on github. So i'm sure others have reviewed the source code for mycelium and lineageOS since they're very popular. But wait! Didn't you just say that you can't trust opensource software because they might release another version with malware in it? Hmmm...
Just the sheer number of programming languages your OS recommendation spans. And you don't see the ridiculous: You understand that your device is too insecure so you apply a bandaid. But those bandaids don't work.
Ok, so please, go ahead and hack my cold wallet which runs on android and has no baseband antennas in it. I'm waiting. (By the way I don't use bitcoin anymore).
Just the first of the tens of repos you linked in that OS has 23 thousand commits. It's not peer reviewed. We are talking about hundreds of contributors that push arbitrary code. VS fucking 6 you retard. It literally took me less than 15 minutes to spot the first memory leak. C++ code is hard.
I heard /masterhacker is hiring. But seriously though, mycelium wallet has around 1200 commits, and lineageOS has over 1,809 repositories. Which one did you check? Because there are a lot of repos for lots of different devices.
No I couldn't. There is a difference. Don't spread misinformation if you cannot grasp that bit of information.
Actually there isn't LOL. You're using big boy words, because you think they sound smarter but they really don't. Any program can be "Binary software", a.k.a, every fucking program that runs on computers. Yes, at the top level the code might be something like C, but at the core its binary, unless you're using something else. But in this sense, its pretty obvious that you don't have to use "Binary software" when you're speaking about an application running on phones.
I get into a hissy fit over you recommending off-topic insecurity practices under the guise of security. Get the fuck out of here. Unlocking a phone alone is usually done by literally trusting criminal hackers doing the deed for you. I don't know if Samsung is on top of their game yet. I get they are doing a great job. I get that some brands come with tools to install custom operating systems. I like HTC.
No, you got into a hissy fit because you're an iOS fanboy. That's your issue. I recommended it because:
It's a cheaper option, since you don't have to buy a new cold wallet to store a few bitcoins.
Anyone can do it.
An offline wallet is secure.
Meanwhile you're recommending people to get an iPhone to use as a bitcoin wallet, when you can't even remove the baseband antennas without breaking the phone apart. A nexus 5 is much easier since you can just pop the back open and pull out the antennas.
But normally you need to root your fucking device to "mod" it. So you are trusting on some zero day that was traded in the blackmarket where someone made a lot of money (illegally) on it. You need to make your device insecure in order to install the OS to begin with.
No you don't. You need to unlock the boot loader, and then you can relock it. You really have zero knowledge about how android operates. Also, there are zerodays for iOS as well. And didn't I mention that you'd use this as a cold wallet? You know, without an internet connection .
Who gives a shit.
Please, simmer down, its just an operating system. You're obviously annoyed by the fact that I mentioned android. Don't be a fanboy. Fanboys suck. I am not a fanboy when it comes to android, because I do know android has its own flaws.
Dude, you have no idea what you are talking about. Don't always try to be so special. Just get a hardware wallet from Amazon. Jesus. Fucking. Christ.
Why? Whats wrong with having an encrypted wallet running on a raspberry pi? Please give me an answer. Unless you have people looking through your junk, you don't need a dedicated bitcoin coin wallet, with closed source code.
Edit: When I am saying I don't want to get into an advocacy debate with you, I mean it. I'll just block you. Respond if you want, but there is a chance nobody will read it. Don't go crying because you had to be a special snowflake, had to do all that complicated stuff on your own (what others call you nerd for) and then get burned. But way more importantly Don't recommend others to do it.
Dude what the hell ? You're gonna block me because I replied to your comment? What's your issue? I'm not even making fun of you right now but do you suffer from autism, or aspergers syndrome? You're taking this way too seriously unlike a normal person. Also, you don't work within OpSec, because you don't sound like a person who works within OpSec. In conclusion, you should get some rest, drink a glass of warm milk, and easy up. Its an operating system, not a dick, so don't take it so hard.

It's said that Bitcoin allows someone to be their own bank. This means that when it comes to money Bitcoin users are only beholden to themselves: no third party can dictate to a Bitcoin user how they may spend their money. However this principle of self-determination also means that when it comes to security Bitcoin users have only themselves to rely upon. There are a wide variety of ways to use Bitcoin, which means that securing Bitcoin is not a one-size-fits-all proposition. Generally though, there are two recommended configurations for using Bitcoins: hot and cold wallets. Hot wallets optimize for ease of spending and movement, cold wallets go the other way and optimize for difficulty of movement to prevent theft.
Hot wallets are where Bitcoin commerce happens, coins can flow in and out with the minimum of resistance needed to prevent theft. There are many use cases where a hot wallet is appropriate: receiving payments from third parties, making small daily purchases at points of sale, regular or bulk fund transfers to generic endpoints, and converting to fiat to send an outside currency.
For receiving payments, it's recommended that the highest levels of validation be used. Even receiving funds from a trusted person may be suspect, the chain of trust is only as solid as its weakest link, if the trusted person re-sends coins from an untrusted third party, then the trusted person's funds cannot be trusted. A strong user flow for this use-case is to use a strongly validating wallet as a proxy. Any funds that are known to have been validated by a strongly validating wallet are safe, even when transferred to a weakly validating wallet: the worst case scenario being that they do not transfer to the weakly validating wallet successfully. Recommended strongly validating wallet:
For sending payments on the go or casual payments online, a mobile wallet is seen as a fairly secure option. Although it's unwise to store large amounts on a mobile wallet due to the risk of device loss or theft, a small amount of money on an iPhone or Android is seen as practical as long as those platforms' default security mechanisms have not been bypassed and well-vetted software is used. Recommended well-vetted mobile wallets:
For transferring larger amounts of funds or making payments from small to large, it's useful to have a wallet that tempers extreme security with ease-of-use. The most effective way to achieve this utility is through the use of MultiSig, a feature of Bitcoin that allows multiple independent signatories to cryptographically sign off on outgoing fund transfers. This method is seen as highly secure: an attacker attempting to purloin funds must simultaneously compromise multiple independent devices in order to perform an unauthorized spend. Other security methods are possible that separate and isolate potential attackers, such as crafting transactions on an offline or single purpose computer, but the inconvenience of those methods may lead to their disuse, whereas a multiple signature flow can be simple and closely follows the general security industry best practice of requiring multiple factors for authentication. Using a desktop wallet for regular spending is recommended, due to the standard desktop security model that places reduced trust in the platform vendor. Recommended MultiSig wallets
A Bitcoin user may stand apart from fiat and never touch it, but in practical reality no man is an island and the necessity or desire to interact with a fiat accepting merchant or a less enlightened individual may arise. To ease this process, custodial wallets and debit cards have been developed as compact convenient fiat exchanges. A user simply stores some Bitcoin with a service; when a fiat spend is requested the service automatically performs a market trade and completes the spend. Although generally speaking custodial wallets are not recommended, in the case of spending fiat they are a practical best solution. Recommended Fiat Spending Solutions
Many users of Bitcoin have absolutely no need to access the majority of their funds on a day to day basis. To take advantage of this fact, these users can dramatically improve the security of their funds by placing them in a difficult to access cold storage wallet. Many solutions have been created for this use case, but generally speaking there are two broadly useful ways to accomplish cold storage: hardware wallets and HD backup seeds.
From a security perspective all software wallets are extremely problematic: they share a platform with other programs, any one of which may be malicious and abscond with user funds. Platform security features, dedicated computers, or software defensive programming can mitigate the problem but from a logical security perspective the surface area open to attack is much wider than absolutely necessary. A hardware wallet device addresses this problem by being designed specifically to be logically separate and single purpose, minimizing risk of unauthorized fund transfer. Recommended hardware wallets:
Every wallet stores a set of data called private keys, these keys are simply secret random numbers that are used to sign all fund transfers. If wallet files are deleted, and no backup is made, this can mean a loss of funds for the wallet owner: since he can no longer sign a transfer, he can no longer spend his funds. To avoid this scenario, all that is needed is a backup of the private keys. Not only is this important for securing funds, it can be used as a method to secure funds in a cold way. By deliberately and securely erasing a hot wallet and keeping the backup out of the reach of any network or computer, the funds are logically separated it from the possibility of remote theft. The best way to accomplish this is a durable and simple system called a Hierarchical Deterministic Seed, or HD seed, a system formalized in Pieter Wuille's Bitcoin Improvement Proposal BIP 32. Essentially, this backup scheme specifies a single random number that is used as a starting seed to deterministically generate a lot of other random numbers, or private keys, to be used by a wallet instead of many individual isolated random numbers that must be collectively backed up. The big advantage to this system is the extreme ease of backup and restoration: a seed can be encoded as a simple set of twelve words, which are easily written down. Users should keep at least three copies of their seed in separate, secure places, inclusive with a software or hardware wallet using the seed. Various mechanisms exist to improve the durability of stored seeds: laminated paper, safe deposit boxes, safes, etc. Writing down the seed is preferable to printing, as printers and the chain of printing may leak a copy along the way.
