Bitcoin

Bitcoin is a new electronic payment system that removes the need for third party financial institutions. It speeds up transactions while reducing costs and minimizing the potential for fraud. The name “cryptocurrency” points to how it uses “cryptographic proof” to work, AKA a blockchain.

Bitcoin’s concept was first introduced in 2008 when a person going by the pseudonym Satoshi Nakamoto shared a white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” In January 2009, the Bitcoin blockchain was launched. 

A new electronic payment system called Bitcoin removes the need for third-party financial institutions. It speeds up transactions while reducing costs and fraud-risk. The name “cryptocurrency” points to how it uses “cryptographic proof” to work, AKA a blockchain.   

Bitcoin has a finite supply of 21 million, which is expected to be reached by the year 2140. Currently, 18.8 million are circulating in the market. Note that Bitcoin represents the concept of the network, while bitcoin (lower-case ‘b’) represents the currency.

Bitcoin is one of the most well-known cryptos as it was the first decentralized currency. 

Currently, BTC’s dominance is above 40%. Bitcoin Dominance is a measure of how much of the total market cap of crypto is made up of Bitcoin. Bitcoin’s influence in the crypto ecosystem could be vulnerable to competition as alternative coins grow in popularity and utility.
