Bitcoin (BTC), as a digital currency, has attracted much attention globally. It was born relying on blockchain technology and has characteristics such as decentralization. However, the price of BTC often fluctuates violently, and investing in it is like being on a roller coaster, with extremely high risks. Moreover, in our country, virtual currency-related activities are explicitly identified as illegal financial activities. Therefore, the public should maintain a rational understanding of BTC and avoid blindly participating in speculation, instead focusing more on legal, compliant, stable, and secure investment areas.
