More and more people have received calls to tax the profits of US stocks and Hong Kong stocks, which is being promoted and implemented on a large scale. Crypto is fine in the short term, but it is also dangerous in the long term. Many people say that China has not declared Crypto legalization, so there will be no taxation. This logic is wrong. Even for illegal gains, the government may impose taxes, such as gambling and smuggling gains. Therefore, even if there is no deregulation of Crypto in China, it is still possible to tax overseas and currency speculation income. It depends on the cost of law enforcement and cost performance.
