#波段交易策略 **Bitcoin (Bitcoin, abbreviated as BTC)** is a decentralized cryptocurrency introduced by Satoshi Nakamoto in 2009. It is based on blockchain technology and issued through a 'mining' mechanism, with a total supply capped at 21 million coins, giving it scarcity and tamper-proof characteristics. Bitcoin does not require support from central banks or financial institutions, allowing users to conduct peer-to-peer transactions directly. Due to its transparency, censorship resistance, and traceability, it is regarded as 'digital gold' and is favored by many investors. Bitcoin's price is highly volatile, with risks and rewards coexisting, and it is controversial due to issues related to money laundering and regulation, but it has become the core asset of the crypto economy.
