The main purpose of the country's ban on speculation in virtual currencies is to prevent potential financial risks. Although such a ban does not directly define speculative trading as illegal, it primarily implements control by restricting the channels for the inflow and outflow of funds.

The reason Sun Yuchen has not faced legal sanctions is that his actions often tread the gray areas of the law, not yet crossing clear legal boundaries. However, investors must still bear the risks of participating in such activities. Speculative trading essentially falls under personal investment decisions, and both profits and losses must be taken on by the individual. Despite the extremely high risks associated with speculative trading, it cannot be denied that the virtual currency sector has played a positive role in promoting the development and innovation of blockchain technology.
