Bitcoin (BTC, ₿) is the first decentralized digital currency and the first cryptocurrency in the world, that doesn’t need any banks or administrators, because it has the peer-to-peer network.
Bitcoin network nodes verify all transactions due to the use of cryptography and recorded in a public distributed ledger called a Blockchain.
Bitcoin was created in 2009 by an unknown person or group of people under the pseudonym Satoshi Nakamoto.
The Bitcoin cryptocurrency token can be received as a reward for a process called bitcoin mining. Or one can sell BTC tokens or exchange for other currencies (including cryptocurrencies, fiat and coupons), products, and services.
