Bitcoin is a decentralized digital currency that works on a peer-to-peer network, allowing users to send and receive payments without the need for intermediaries such as banks or governments. It is said to have been invented in 2008 by an unknown person or group of people under the alias of Satoshi Nakamoto. However, it was released as an open-source software in 2009. Bitcoin's price has risen dramatically since its inception, and some investors view it as a hedge against inflation or a store of value like digital gold. Bitcoin investment also allows for portfolio diversification because its price movements differ from those of traditional assets such as stocks, bonds, and mutual funds.
