#美国加征关税 BTC is the abbreviation for Bitcoin. It is a decentralized digital currency and payment system created by Satoshi Nakamoto in 2009. Here are the specific details:

• Technical Principle: Bitcoin is based on blockchain technology, uses the SHA-256 algorithm, and follows the PoW (Proof of Work) consensus mechanism. It relies on a distributed database confirmed and recorded by numerous nodes in a P2P network, ensuring transaction security through cryptography.

• Issuance Mechanism: Bitcoin does not have a specific issuing authority and is generated through 'mining.' Its total supply is limited to 21 million coins, with block rewards halving as mining progresses, expected to be fully issued by the year 2140.

• Characteristics: It has features such as decentralization, scarcity, and anonymity. It does not rely on a central bank or a single administrator, allows for instant payments globally, and transaction records are transparent and immutable on the blockchain.

• Price and Market: The price of Bitcoin is highly volatile. As of February 12, 2025, its price is approximately $105,941.49 per coin, with a market capitalization of $2.1057 trillion and a circulating supply of 19.88 million coins. On June 6, there was a significant price drop, falling below $101,000 per coin, with a daily decline of 3.55%.

• Application Scenarios: It can be used for peer-to-peer electronic transactions, purchasing goods or services, and can also serve as an investment target, regarded by some as a means of value storage, similar to 'digital gold.'

However, the legality of Bitcoin transactions varies in different countries and regions. In China, a notice was jointly issued by five ministries in 2013, clarifying that Bitcoin is a virtual commodity, prohibiting financial institutions from intervening, but allowing ordinary citizens to participate in trading at their own risk.
