Bitcoin
It seems like you will not be able to trade in some cryptocurrency any time soon in China, it has been illegal for some time now. They are not easing up on their original decision either, they doubled down in 2021 and claimed they will try to root out all traces they can find of crypto trading.
So much for investing in Bitcoin, well of course you can still do it if you live outside of China and assume that you can even afford Bitcoin anymore. It makes us remember the days when we heard about Bitcoin in its earlier stages but were too lazy or unconvinced to invest.
