#MarketCorrectionBuyOrHODL #Bitcoin[ar 1] (abbreviated BTC; symbol: ₿) is the first decentralized cryptocurrency. It can be sent from person to person over the Bitcoin network in a peer-to-peer manner without the need for a third party. Network transactions are verified using cryptography and recorded in a distributed ledger called the blockchain without a central authority to oversee them. Consensus between nodes is achieved using a computationally intensive proof-of-work process known as mining, which secures the Bitcoin blockchain. Mining consumes large amounts of electricity and has been criticized for Bitcoin's environmental impact. Based on free-market ideology, Bitcoin was invented in 2008 by an anonymous person known as Satoshi Nakamoto.[6] Bitcoin began to be used as a currency in 2009,[7] when its application was released as open source software.[8]:ch. 1 In 2021, El Salvador adopted it as legal tender.[9] It is often viewed as an investment and has been described by many scholars as an economic bubble.[10] Because Bitcoin is used under pseudonyms, it has been used by criminals, which has drawn the attention of regulators, leading to its ban in several countries as of 2021.
