Historic data shows that bitcoin has only way to go - up.

But, it's only this year that we're having too many forks and FOMO driven price action (bitcoin cash, bitcoin gold, segwit2x, China ban, Jamie Dimon) and I think this kind of frenzy must stop and some amoutn of sanity driven rise is needed. Plus if we're looking at Bitcoin as a real alternative currency, how would one even feel like using it with this amount of volatility? You'll end you just having hodlers and not users - one guy selling it ot another guy for a higher price and he selling it to a third person for an even higher price and and that's how bubbles are created...
