Bitcoin is a decentralized cryptocurrency created by Satoshi Nakamoto in 2009. It is based on blockchain technology, providing a secure and transparent transaction method without the need for traditional financial intermediaries. The main features of Bitcoin include:

Decentralization : There is no central authority controlling it, and transaction records are distributed across nodes worldwide.
Security : Transactions are secured and immutable through cryptographic technology.
Anonymity : While transaction records are public, user identities can be kept anonymous through encrypted addresses.
Limited Supply : The total supply is capped at 21 million, with new coins released through mining, reducing inflation risks.
Bitcoin has a wide range of applications, including investment and online payments and transfers. However, it also faces challenges such as regulatory uncertainty and price volatility.
