Well, I guess it's not. New rich people is coming :^)
Do you know of any people that went bankrupt because of crytos? I read an old thread on Bitcoin talk, after Googling the subject, and this one guy lost like $400,000 of his retirement. Hadn't told his wife yet. But this was many years ago, so hopefully he hoarded some Bitcoins and recouped.
That's why you shouldn't shit through Bitcoin, even though it has a potential. Keep in mind, that Bitcoin market is really risky and by doing that you are agree to take the risk and responsibility.
