I do believe we are in some bubbly state right now. Knowing that crushes comes every like 10years it could be psoible that this decade it be crypto market, maybe won't. But crypto market does have some patterns of the bubble, if not big as housing market at least it has smaller bubbles. Because it being high risk investment you have big players such as Jack Ma or yet even Buffet don't like bitcoin much to get more money as they are going and aiming for sure things.
