What is Bitcoin (BTC)?

Bitcoin is a digital currency with a fixed total supply of 21 million, characterized by decentralization, globalization, and anonymity, similar to the Internet. Transferring Bitcoin to the other side of the world is as simple as sending an email, with low costs and no restrictions. As a result, Bitcoin is used in areas such as cross-border trade, payments, and remittances. Bitcoin is a type of electronic cryptocurrency that operates on a decentralized, globally accepted basis, without the need for third-party institutions or individuals, based on blockchain technology as a payment method. From an operational standpoint, Bitcoin is essentially a decentralized ledger on the Internet.
