Bitcoin is a cryptocurrency that was launched in 2009. It is a form of digital currency that is issued and managed through a decentralized network without a central authority or bank responsible for it. Unlike traditional currencies controlled by governments, Bitcoin is an open-source project managed by a community of developers and users.
Bitcoin uses a technology called blockchain to verify and store transactions. Each transaction is grouped into a block and linked with other blocks to create an immutable, public record. This technology allows Bitcoins to be securely transferred without central control.
Bitcoin has gained popularity in recent years and is now a well-known form of digital money. It is often considered as an alternative investment option and can also be used as a means of payment. However, it is important to note that Bitcoin is still a very volatile and rapidly changing concept and there is still much uncertainty about its future and its value.
