The first blockchain-based cryptocurrency was Bitcoin, which remains very popular and very important. Today, there are thousands of other cryptocurrensets with various functions and specifications. Some of them are clones or forks for Bitcoin, while others are new currencies built from scratch.


Bitcoin was founded in 2009 by a person or group known by the pseudonym "Satoshi Nakamoto." 1 As of August 2021, there were more than 18.8 million bitcoins in the stream with a total market capitalization of about $ 858.9 billion, the number being repeated several times.

As of August 2021, the combined value of all existing cryptocurrencies exceeds $ 1.8 trillion - Bitcoin currently represents approximately 46.5% of the total value.3
