Bitcoin is the most popular and valuable cryptocurrency. An anonymous person called Satoshi Nakamoto invented it and introduced it to the world via a white paper in 2008. There are thousands of cryptocurrencies present in the market today.
Each cryptocurrency claims to have a different function and specification. For example, Ethereum’s ether markets itself as gas for the underlying smart contract platform. Ripple’s XRP is used by banks to facilitate transfers between different geographies.
Bitcoin, which was made available to the public in 2009, remains the most widely traded and covered cryptocurrency. As of November 2021, there were over 18.8 million bitcoins in circulation with a total market cap of around $1.2 trillion. Only 21 million bitcoins will ever exist.
In the wake of Bitcoin’s success, many other cryptocurrencies, known as “altcoins,” have been launched. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch. They include Solana, Litecoin, Ethereum, Cardano, and EOS. By November 2021, the aggregate value of all the cryptocurrencies in existence had reached over $2.1 trillion—Bitcoin represented approximately 41% of that total value.
