Bitcoin (Bitcoin) wallet, how to use?


Bitcoin or Bitcoin is an electronic payment system based on the work with the cryptocurrency of the same name - Bitcoin.

In this article, we will analyze the process of working with Bitcoin as an EPS, namely: choosing and creating a wallet, the main advantages and disadvantages, a security system, registration, and more.

Bitcoin: an overview of the electronic payment system

As you know, Bitcoin combines two inextricably linked concepts:

  1. Bitcoin (Bitcoin) is a decentralized system of electronic financial settlements on the network.
  2. BTC, bitcoin is a monetary unit of account.

The idea of creating Bitcoin belongs to an anonymous developer, who in 2008 published a scientific article under the name of a certain Satoshi Nakamoto, describing the theoretical foundations of the system based on cryptography and programming.

Bitcoin as EPS is no different in its way of working from all other EPS: just like using the well-known PayPal system, you make transactions in US dollars, in the same way you use the Bitcoin system, making transactions in BTC.

Bitcoin wallets

In order to freely and fully dispose of the Bitcoin system, it is necessary to create a special functional client - a bitcoin wallet.

There is a common misconception that a bitcoin wallet is a long string of Latin letters and numbers (for example, 159TFgyRhrSsddZaL6PGdsgyzh6gxuSc7k). In fact, this is the public address of your bitcoin wallet, and there can be as many such addresses.

The wallet itself (in the basic sense) is a regular file that stores information about all your addresses. This file is managed by a special program. Hence the conclusion: a bitcoin wallet is a file and a program controlled by it.

Choosing a bitcoin wallet is a very important task that needs to be approached judiciously and seriously. A good and reliable wallet must meet two essential criteria:

  1. The wallet must provide proof of bitcoin ownership. Responsible for this item is the so-called. a private key that is created by the program and corresponds to a public address. It is the secure storage of private keys that ensures the safety and reliability of your funds.
  2. The wallet should allow you to freely manage your money at any time.

Now let's look at the types of wallets. At the moment, only 5 types are known:

  • Web wallets (online wallets);
  • Mobile;
  • Local (desktop, offline wallets);
  • Hardware;
  • Paper.

Each type of wallet is characterized by its own characteristics, but we will talk about the advantages and disadvantages of the two most used types: onaylan and offilan wallets.

Advantages and disadvantages of working with Bitcoin in general

The main advantages (in the face of principles) of working with the Bitcoin network:

  1. Decentralization. Bitcoin is not controlled by any person, company or state. All transactions are peer-to-peer, that is, independent of the central server, in nature.
  2. Anonymity. There is no personal data in the Bitcoin system. Much depends on the choice of the wallet, since in some cases partial or complete confirmation of identity is required. Nevertheless, most wallets try to ensure the confidentiality of personal data.
  3. Reliability and safety. The probability that Bitcoin will be susceptible to hacker attacks is practically zero. Withdrawing money from the wallet or blocking it by the system in Bitcoin is impossible.
  4. Low fees. Commissions have been introduced to rank transactions by processing priority. Generally speaking, most transactions can be made without commission - this is a voluntary matter, but then the priority of processing such transactions will be the lowest.
  5. Transparency of calculations. The details of all transactions are publicly available and stored in a special database - the blockchain. They cannot be deleted, and knowing only one bitcoin address, you can find out all transactions received or sent from it.
  6. 24/7/365. Bitcoin works 24 hours, seven days a week and 365 days a year without weekends and holidays. If you wanted to make a translation on January 1 at 5 am, then it will be so.
  7. No boundaries. Bitcoin works anywhere in the world where there is Internet access (and sometimes even not required).
  8. Division into coins. This allows for microtransactions, even thousandths of a dollar is not a problem.

The main disadvantages of working with the Bitcoin network:

  1. Lack of chargebacks. Bitcoin does not support its customers. Therefore, if you make a mistake when entering the address, enter the wrong amount, lose access to your wallet, or your hard money breaks, you will lose your bitcoins without a trace and you will have nowhere to turn for help. In addition, transactions cannot be canceled.
  2. Direct dependence on BTC. The Bitcoin network is completely dependent on the currency itself: if Bitcoin suddenly depreciates, the network will lose its relevance and become meaningless.
  3. Delayed transactions. Transactions do not go as fast as we would like, and you have to pay to increase the priority.

Methods to protect Bitcoin wallets

  • Encryption - Users can encrypt their data using a special program or the Encrypt Wallet function. Encryption reduces the likelihood of a wallet being hacked, but does not provide a 100% guarantee.
  • Backing up is one of the best ways to protect yourself. Always make backups of your wallet and store them on different media (flash drives, portable drives). This will not only protect you from computer system errors, but also help restore the wallet if it was lost for any reason.
  • Complex passwords and two-factor identifications. Passwords on bitcoin wallets must include at least 8-10 characters (letters with numbers). Two-factor identification will provide these wallets with additional protection.
  • "Cold storage" (Cold Storage). You can keep the bulk of your money offline, without network access. At the moment, this is the best way to protect against hacker attacks.
