It is possible that at some point crypto would somehow be regulated by the government "if" crypto reaches mass adaption, to the point where Fiat money becomes useless. But i dont see it happening anytime soon, it would take several years before that happens, for now i'm not quitting crypto just because of this speculation. It's too early to say this kinds of stuff. Yes, the government is taking notice of cryptocurrency, but with the minority of its users I dont see any kind of action that the government is starting to "control" crypto.
