What Is Bitcoin?
Bitcoin is a decentralized digital currency that operates without a central authority, using cryptography to secure transactions and control the creation of new units. It is the most prominent cryptocurrency, alongside alternatives like Bitcoin Cash, Ripple, and Litecoin. This guidance focuses on Bitcoin’s tax implications, though other cryptocurrencies may differ in features and tax treatment.
