If China wants to crackdown Bitcoin mining activities, miners will go elsewhere. This is actually a good thing for cryptocurrencies, as it shouldn’t be under a decentralised, power-obsessed regime. China can play with its digital yuan.
China government to many things to protect their regime, not their people or the world, see FUD from China as simple as that, you will see your journey with Bitcoin and China FUD more easily.
If you look at lowest price of Bitcoin, on yearly basis, you will see Bitcoin is always moving up, almost all years (one year, 2015, has negative change compares to 2014). Stay positive as FUD will disappear after all.
Please notice the lowest price in 2020, we are many times higher than that min price, still uptrend.
