The tax issues related to virtual currency speculation were actually mentioned a few years ago in tax reports, stating that profits from speculation should be taxed, but there has been no follow-up on how to implement it.

Recently, when cracking down on overseas gains from the US stock market, there was also proactive disclosure of issues, resulting in taxes being levied on cryptocurrency trading.
Essentially, the user data from exchanges is now inaccessible to the government, and exchanges probably don't want to provide certain tax-related data to the authorities. After all, whether it's US stocks or A-shares, market volatility is high. If crypto trading also requires paying taxes, fewer people will participate.
So this game of cat and mouse will continue until one day some government gets access to the data, and then the fun really begins.
It's important to note that some years are very difficult to make money; the crypto circle mainly profits during one or two bullish years. When taxes are finally collected, after calculations, it might still result in a loss.
Regarding Xu Mingxing, who do you think was the first to provide user tax data?
