Bitcoin wallet is the equivalent of a physical wallet for transactions with Bitcoin. There are different wallets for different platforms. To start working with bitcoins (Bitcoin), first of all you will need a bitcoin wallet. It allows you to make transactions, that is, buy and sell cryptocurrency. The main task of bitcoin wallet is to store the secret key that is needed to access the bitcoin address and, accordingly, your funds. From a technical point of view, bitcoins themselves are not stored anywhere, only secret digital keys are stored, which give access to public bitcoin addresses and the ability to «sign» transactions. It is for this information and need a bitcoin wallet. Wallets are different, depending on the device for which they are intended — you can even do not use the computer and write the keys on paper. And, of course, it is very important that the wallet has a backup copy and was protected from unauthorized access. [1]

Cryptocurrency wallets are digital and physical, offline and online methods that rely on public key cryptography [2] to allow users to send and receive bitcoins securely across the network.

What is a Bitcoin wallet? [ edit ]

Bitcoin digital wallet uses public key cryptography to make transactions secure. Public key cryptography is a system in which a piece of data is encrypted with a public key, and can only be decrypted using the public key’s matching private key. [3]

BTC wallet can be a software, hardware, online web service, or piece of paper, that works by generating the public-key-and-private-key pair necessary for users to engage in a transaction, i.e. to transfer value between Bitcoin wallets and include this information in the blockchain. [4] The public key – also called an address – and the private key – also called the seed – are large integer numbers usually represented using a separate Wallet Import Format (WIF) consisting of letters and numbers. [5] Each public key should only be used once. While the address is public, the private key should only ever be seen by the owner of the wallet and never shared with other people.

When a user wishes to send bitcoins, their private key is combined with the transaction request (which includes the receiver’s public address) to encrypt or digitally «sign» it. [6] The digital signature produced is important because it provides the nodes in the network with the mathematical proof they use to verify the authenticity of the source and check that the sender actually has the right amount of bitcoins to spend. In the blockchain, all bitcoins are registered to an address, or public key.

The main functions [ edit ]

Bitcoinwallets provide the following functionality:

• storage of Bitcoin addresses and corresponding closed/open keys on users computer in wallet.dat file.
• conduction transactions of obtaining and transferring Bitcoins (BTC), also without connection to internet
• providing information about the balance in BTC at all available addresses, prior transactions, spare keys.

To set up a Bitcoin wallet you need to choose a wallet provider, to go through a registration procedure and to verify an email address. [7]

Bitcoin Core [ edit ]

The original Bitcoin client stores private key information in a file named wallet.dat following the so called bitkeys format.

• user preferences
• default key
• reserve keys
• accounts
• a version number
• Key pool
• Since 0.3.21: information about the current best chain, to be able to rescan automatically when restoring from a backup.

The wallet.dat file is located in the Bitcoin data directory and may be encrypted with a password.

It is intended that a wallet file be used on only one installation of Bitcoin at a time. Attempting to clone a wallet file for use on multiple computers will result in weird behavior. [8]

The format of this file is Berkeley DB. Tools that can manipulate wallet files include pywallet.

Types of Bitcoin (BTC) wallets [ edit ]

Wallets can be classified according to whether they are physical or digital, or according to whether they are online or offline. Hardware Bitcoin wallets and paper wallets are physical. Digital wallets can be mobile or desktop software, or web services. All these wallets are either by default, or could potentially at some point be, online. A hardware and paper Bitcoin wallets are meant to be used offline (cold storage). However, one could connect a hardware wallet to, or print a paper wallet from, a computer that was online. Doing this is counter-recommended since it would void the whole purpose of these wallets. A software wallet may be used online or offline. Web wallets are always online.

12 Best Bitcoin Wallets to Store Your Coins Safely

In this article we present the best Bitcoin wallets, for ultimate security and convenience.

Bitcoin is only truly yours if you know how to store it!

Sure, buying Bitcoin and leaving it on your exchange wallet is one option, but then you are never in full control of your funds.

In this article, we will show you the best Bitcoin wallets on the market and help you select the one that best suits your needs.

After reading this post, you will know what makes a great wallet and it will be easy to make your final choice.

What is a Bitcoin wallet

A Bitcoin wallet is a software program that allows Bitcoins to be stored.

Each time you buy Bitcoin, the platform or individual you buy your coins from, will ask for the address of your Bitcoin wallet. There are many different wallet options, which we will discuss below but for now, let’s see how a Bitcoin wallet works.

How a bitcoin wallet works

Most people assume that their coins will be sent and stored inside of their digital wallet, much like you would store paper bills in your physical wallet. In this case, however, the truth is a little bit different.

You see, when observed from a more technical point of view, Bitcoins are not really “stored” anywhere. When you create a crypto wallet, you essentially create a secure “access points” for a specific coin balance.

A Bitcoin wallet consists of two codes:

• A private key, which allows wallet owners to access and use their Bitcoin balance.
• A public address, which allows wallet owners to receive or request Bitcoin to the wallet.

Both of these keys are shown in long, alphanumeric codes, that are randomly generated and make each wallet completely unique.

As such, and to be more precise, Bitcoin wallets give you ownership over a certain Bitcoin balance. The proof of ownership is possible thanks to blockchain technology, which removes the danger of double spending and makes every transaction fully transparent.

How to choose the best Bitcoin Wallet?

Now that you have a better understanding of how a Bitcoin wallet works, it’s important to differentiate the different categories of wallets. Generally speaking, there are four main categories:

• Online wallets, which allow your funds to be stored online. These are convenient, easy to access from any device and make Bitcoin transfers very simple. Online wallets are also often referred to as mobile wallets since they also come in the form of an app.
• Desktop wallets, if you prefer to store your funds on a single device. These are more secure than online wallets and turn your PC into a security vault.
• Paper wallets, if you rather store your funds offline. When using a paper wallet, you simply use a printed version of your keys to store your funds away from any digital device.
• Hardware wallets, if you want maximum safety and secure transactions. Hardware wallets are the most popular option, thanks to their physical nature and manual authorization.

1. Best online wallet – Blockchain.com

Choice of coins: 5
Access: Mobile and Web
Operating system (for mobile): Android & iOS

Blockchain Wallet is one of the most popular Bitcoin wallets currently available. Ever since 2011, the wallet has been offering secure storage options for both Bitcoin (BTC) and Ethereum (ETH) investors. In recent times, the wallet has also created support for BCH, XLM, and PAX.

So what makes this wallet unique? Let’s dig into the nuts and bolts.

What can you do with Blockchain wallet?

The wallet offers several benefits for their users, whether those are functional or aesthetic in nature:

• You are able to login to your wallet by simply entering a 4-digit pin code , much like you would access the bank account app. If you worry about security, you have the option to add more layers of security, such as 2-step Verification, fingerprint lock or an additional password.
• Check the value of your funds in your local currency . Aside from that, a pie chart will indicate the distribution of your funds so you maintain a clear overview of your investments at all times.
• Buy and sell coins directly from the wallet. When you create a new wallet you will be able to go through KYC to whitelist your wallet. Once that is done, you will be able to purchase and sell cryptocurrency directly from your wallet app.
• Send crypto with one click. A handy QR code logo on the top-right corner of the screen will allow you to send funds to any QR-based crypto wallet in seconds.
• Use as an online wallet or mobile app. You can access your wallet by logging in on blockchain.info or download the app directly on your phone

2. Best desktop wallet – Armory

Choice of coins: 1
Access: Desktop
Operating system: Windows/Mac OS/Linux/Ubuntu/Debian

There are many desktop wallets but only one has captivated our hearts. Armory offers the highest level of security when it comes to Bitcoin desktop wallets. It is more aimed towards advanced users and institutional investors that deal with larger amounts of money, but can also be used by anyone else.

What makes Armory the best option?

• Offline storage options , which are pioneering s far as security is concerned. You are able to create your wallet while offline and ensure that your funds are safely stored.
• Multi-signature transactions , for additional security. In simple words, the wallet owner cis able to appoint a second person as an additional confirming party before the funds are transferred.
• GPU-resistant wallet encryption. Armory uses what is more commonly known as the “key-stretching” method. This requires an amount of computing memory that is small for regular processors, but too big for a GPU.
• The wallet is open-source. Armory was built with developers in mind. As such, it makes a great base for building Bitcoin applications, like crowdfunding platforms or exchanges.

How to set up your Armory wallet

3. Best Hardware wallet – Ledger Nano S

Choice of coins: 1250+
Access: Ledger device
Operating system: Windows/Mac OS/Linux

Hardware wallets have become very popular over the last few years. This is not because of their pocket-sized shape, but also due to their high level of security. Among the top options, one wallet stands out, even though it’s not the newest in the market. We are talking about the Ledger Nano S , one of the first and Best Bitcoin wallets.

Bellow, we will explain the key factors that made us choose the Ledger above any other hardware wallet option.

Why should you choose a Ledger Nano S?

• Provides the highest level of security. All ledger products are built with a certified secure chip and a custom OS to provide the highest level of security.
• Supports more than 1250 cryptocurrencies , including Bitcoin. Ledger wallets support all the popular cryptocurrencies as well as all ERC-20 tokens.
• Convenient management with the Ledger App. Download and use Ledger Live together with your wallet to check your balance or exchange your cryptocurrencies.
• It is the most popular hardware wallet on the market. With more than 1,500,000 units sold, Ledger Nano S wallets are the most popular hardware wallets in the market.

The following video takes you through the process of setting up your Ledger Nano S:

4. Best Paper wallet – Bitaddress

Choice of coins: 1
Access: N/A
Operating system: N/A

As mentioned above, this type of wallet is essentially a sheet of paper that contains both your private key and public address. Paper wallets are often printed in the form of QR-codes so that you can quickly scan the address and make a transaction. There are many different services that are used for this particular purpose, but the one we prefer to use is Bitaddress . The website allows users to generate random Bitcoin addresses, each with unique private keys. Once created, these wallets need to be printed and stored securely to ensure the safety of one’s funds.

What makes paper wallets worth considering

• Great for HODLers . Many people are often drawn away from paper wallets due to their relative complexity when it comes to transactions. If users want to send some of their funds they will first need to transfer the whole content of their wallet into another wallet (that allows users to send specific amounts of their Bitcoin). However, this can also act as an advantage. Being unable to transfer small amounts of funds while holding funds into a paper wallet makes users hold onto their Bitcoin unless selling is absolutely necessary.
• Creative security. When you create a paper wallet, only you are responsible for its security. Some people will choose to laminate the paper and store it into a secure location. Others will implement a strategy known as sharding , to make things even safer. Overall, it’s best that you have at least some sort of strategy when it comes to the storage of your paper wallet.
• Budget-friendly. If you are looking for hardware wallet-grade security but don’t have the funds to afford one, you can consider using a paper wallet. Both options store one’s funds offline and ensure 100% protection from any type of hacking attempt.

Other great contenders for the title

1. Trezor One – The Trezor One follows Ledger Nano S very closely in being the best hardware wallet. You can check its features by checking out this page .
2. KeepKey – Shapeshift’s very own hardware wallet is both stylish and very secure. If you are looking for an alternative to the most popular choices, this is the one to consider.
3. Exodus – This desktop wallet has a stylish design and is a very popular option to store Bitcoin. However, it is not able to store funds offline or offer the multi-sig option.
4. BitcoinPaperWallet – BitcoinPaperWallet is the second most popular paper wallet. The reason we did not choose it as our top option is that most guides and tutorials on the web use Bitaddress as an example. This would make BitcoinPaperWallet a little harder to understand by beginners.
5. Coin Wallet – Being the best online wallet option on Bitcoin.org, Coin Wallet is certainly no new player. This online wallet is as simple as it goes but offers everything you need to store your funds online safely.
6. Electrum – This desktop wallet allows you to print a set of your recovery keys and turn a simple wallet into a super-safe vault. It is also very easy to use and fully encrypted.

Best Bitcoin wallets – Frequently asked questions

What is a Bitcoin wallet address?

A Bitcoin wallet address is also known as a public key. This key is can be found in any type of wallet when you want to send money to your wallet or request funds. The length of each wallet varies, due to their encoding, but you will always recognize them from their appearance – a random combination of letters (upper and lower case) and numbers.

What is a Bitcoin wallet private key?

A private key is similar to a password used to enter your account. It helps users access their account so they can send their bitcoins to others. Similar to public keys, this address is a random combination of letters and numbers.

What are the cheapest Bitcoin wallets (hardware wallets)?

Hardware wallets can get quite pricey, especially when you are a new investor. For that reason, you can choose one of the following budget options.

• Ledger Nano S ($65 for one device)
• Trezor One ($65 for one device)
• KeepKey (10$ for one device – Requires membership on Shapeshift )

What is the safest and most secure Bitcoin wallet?

Due to their purpose, all Bitcoin wallets come with a high level of security. However, some come with additional layers of protection and store your funds offline (cold wallets). These wallets are the best ones to consider when it comes to safety. Here is our top 3:

All the above wallets store your funds in Cold Storage. This means that there is no possible way for your wallet to be hacked by anyone.

Are Bitcoin wallets safe & secure?

Yes. Bitcoin wallets are created to help users store their funds in safety. When using one of the wallets suggested above, you can rest assured that your Bitcoin is safe. Of course, as aforementioned, some wallets are better than others. For that reason, if safety and security are your highest priority, it is best to not use online/mobile wallets.

Which Bitcoin wallet has the lowest fees?

The only wallets that will charge fees when sending or withdrawing your Bitcoin are exchange-based wallets. Therefore, it is best to not store your coins on any platform. The wallets we compared above do not charge any fees. The only amount you need to pay in addition is the transaction fee, which is paid to miners in order to confirm your transaction.

Why does my Bitcoin wallet contain multiple addresses?

As aforementioned, some Bitcoin wallets act simply as keys to your funds. A hardware wallet, for example, will allow you to access your funds from different Bitcoin wallets, all of which are created with the help of your device. Splitting your funds over multiple addresses is also a great practice to ensure that your wallet does not become a target for cyber-criminals.

Can a bitcoin wallet be hacked?

With the progression of technology, there is always a chance that Bitcoin wallets can get hacked. This is why most wallets offer additional security layers. Hardware wallets will also update their hardware from time to time, in order to ensure the safety of your funds.

The wallets that are most often hacked are online wallets. This is because users often use the same password they use for other accounts (social media profiles, email) and do not enable any additional security measure.

Can Bitcoin wallets be traced?

Yes, but with a certain limitation. As of now, there is an active effort by all exchanges and online wallet providers to “whitelist” Bitcoin wallet addresses. This means that the address of your wallet will automatically be linked to your name and personal information. However, as of right now, most wallets are still only recognized by their public key, and there is no further information on their owners. This offers a relative level of anonymity.
