# Cryptocurrencies

Cryptocurrency (English. Cryptocurrency ) is usually an anonymous decentralized digital currency, the issue and circulation of which are based on the participation of most participants in the system and full encryption. All transaction data is usually available to anyone and stored on the blockchain.

Cryptocurrencies such as Bitcoin (Bitcoin or BTC), Ethereum (Etherium or ETH), Doge, Cardano (ADA), Bitcoin Cash (BCH), and others are independent of any government agency or bank. Each participant in the system can transfer funds in it to other participants completely anonymously and such transactions (as well as the issue) do not depend on regulatory authorities or banks.

Bitcoin is the first and most popular digital cryptocurrency. In 2017, its price increased 12 times, and during the beginning of 2021 – twice. Bitcoin was created in 2009 by a mysterious programmer or group of people named Satoshi Nakamoto. Nobody knows who it is and what it is actually called. Since 2011, Satoshi has not been in touch with anyone.
