it's an old problem, that's what makes bitcoin full of pros and cons. although there are several countries that prohibit the use of crypto, there are still many countries that allow it, some even have discourses on creating their own crypto currency. see, although many prohibit transactions or payments with crypto, investment and trading are still allowed, this shows that crypto is indeed very potential, on the other hand there is a side that is less profitable for the government. so this is not a problem, usually legality issues come up every year, creating waves in the market, but no need to worry.
