You tell us many and many things, and hear these things i am not happy, because in this forum you hear everyone said that bitcoin has a bright future, and you are Chinese and you know about bitcoin very well than others, and also you are saying, bitcoin has no live long life, than what's happen with us? If your government suddenly ban the bitcoin. Definitely i have heart attract if it will happen.
Everythings will happen. I will not all-in crypto world. Just invest the appropriate proportion of the portfolio for crypto assets.
Don't all in. take 5%-10% percent of your Investable assets for it. If you need, some gold in 5-10% percent are good too.
then you will sleep well.
(btw, The stock marcket around the world are not the good choice.)
