Bitcoin wallet is an online service, program, application or device for storing and performing operations with Bitcoin cryptocurrency. Technically, at its core, a bitcoin wallet is two keys - one private, and the other public.

You can tell the public key to anyone, it is the address and identification number of your wallet. Payments and receipts of bitcoins from other senders come to this wallet number, and you also send satoshi and bitcoins to other users from this number. The address of your wallet, it is also the public key consists of 34 characters. When making operations, for example, when replenishing your wallet, you should carefully monitor that you indicate exactly your address. For security reasons, do not use Ctrl + C - Ctrl + V when specifying your address during wallet replenishment and other operations, but it is better to use on-screen address input methods. In addition, I advise you to always check the first and last addresses of yours after you have indicated it. The fact is that many scammers use viruses that, when using the manual keyboard, replace your wallet address with their Bitcoin wallet, and send all your funds to your wallet. Also, for security reasons, many Bitcoin wallets have an updated address, and if you wish, you can change the wallet address for each transaction to reduce the likelihood of replacing the address of your Bitcoin wallet with a fraudulent one.
The second key and number is private, which can not be transmitted to anyone, it’s your password from the wallet. The one who owns the private key is the only owner of the bitcoin wallet and only he has access to bitcoins. That is, you own your bitcoins only when you own the private key of the bitcoin wallet. For security reasons, the private key of the wallet should not be stored on electronic media, but memorized and written somewhere on a piece of paper so that your bitcoin wallet does not fall into the hands of attackers.
Types of Bitcoin Wallets. Which wallet to choose?
To create a wallet, you do not need a passport or any other identification documents, so the technology of blockchain and bitcoin is anonymous. Most often it will be necessary to come up with a password and provide your e-mail address. But, before registering and creating a Bitcoin wallet, you need to deal with the whole variety of Bitcoin wallet and their features.
At the moment, it is customary to distinguish four types of Bitcoin wallets:
Some still additionally distinguish a paper bitcoin wallet as a separate type. It is also worth noting that most popular bitcoin wallets are multi-platform, that is, they support several types at once. For security, storage and management of large amounts, the wallet https://bitcoinofficial.org is suitable.
Computer Bitcoin Wallets (Local)
Computer wallets, or as they are also called local wallets, are a software application installed on a PC for various operating systems from Linux to Windows. This type of bitcoin wallets is characterized by the highest security among free types of bitcoin wallets. Computer wallets are also divided into two types, these are thick and thin wallets.
Thick wallets are full-fledged wallets in which the complete base of blocks of the Bitcoin system is downloaded and their reliability is checked. This type of wallet is considered more reliable, since in this case all private keys are stored on your computer in encrypted form. One of the most popular and secure bitcoin wallets in the world is the Bitcoin Core wallet. However, it has a minus, which is hard not to notice - this is the amount of disk space on your computer required for the database of all blocks. The Botcoin Core wallet fully synchronizes and downloads the cue ball database, and at the moment it is more than 250 GB and continues to grow. Therefore, for those who have little free disk space on the computer, this option will not work. Also, to increase the security of the Bitcoin Core wallet, I recommend also installing the Armory application, which enhances the privacy and functionality of the Bitcoin Core wallet.
For those who have limited free disk space, a thin wallet is suitable. This view is a lightweight version that has a different system for interacting with blocks, synchronization will occur through the developers server of the wallet itself. From here two advantages of a thin wallet follow - it is faster work speed and less load on PC resources. But it is worthwhile to understand that due to the dependence on the developer's server, this type is less secure than a thick wallet, but still with a high level of protection. The most popular and safest thin wallet among others is Electrum.
Hardware (as a separate device)
This type is the most protected of all possible types of wallets. Yes, of course, you will have to pay about a hundred dollars for it, but using it you can be sure about the safety of your money. The hardware type of wallet is essentially similar to a regular wallet and is a separate device resembling a flash media. The security of this type of wallet is ensured by the fact that it is impossible to access it remotely through online access. Hacking it is only possible by stealing from the owner, and that is not a fact. Due to the high security, hardware wallets are most suitable for large investors and storing large amounts in bitcoins. A minus in addition to the paid device is its not convenient for conducting a large number of daily transactions. Suitable for storing large savings.
The most popular hardware wallet is Ledger Nano S and Trezor. The first device is more affordable, and its delivery is possible anywhere in the world. Despite the high security of these devices for storing bitcoin, I recommend that you familiarize yourself with the main vulnerabilities of these wallets and security rules in order to avoid hacking the wallet.
Web (Online Wallets)
This type is very popular among those who often operate with small amounts of several satoshis. This type of wallet has a web interface, and therefore differs in speed and ease of use. Web wallets are most understandable for beginners and do not require any significant knowledge in this topic. In addition, web wallets do not require downloading and storing large block databases, which leads to even greater speed of use.
Mobile Bitcoin Wallets
For a mobile device, the application is downloaded just like a PC. However, due to the limited physical space, the entire database of system blocks is not downloaded here. Therefore, in essence, mobile wallets are similar to lightweight versions of local wallets for PCs. The most popular and most secure wallet for the computer Bitcoin Core separately created a version of its wallet for mobile devices and called it Bitcoin Wallet.
