Mark my words: this will all come crashing down. I can't tell you when or why, but it's not sustainable. Probably it will happen in a way that makes the bitcoin nerds "right" in some sense of personal justice: the PRC will close the great firewall to bitcoin traffic, or backdoor the protocol in some unsupportable way. Or the SEC will shut it down somehow.
So sure: when the crash happens cryptocurrency "would have worked" if not for the meddling government. But it will fail nonetheless, and all those people (again, most of whom are not investors in scams like bitqyck) are going to lose all their "money".
