It is quite possible, but we will know this only when this bubble bursts. The question is, how long can this bubble last?
Bitcoin isn't a bubble,and if you feel if is,then leave the system,this is a network that has to do with adequate trading strategies in order to avoid loss, it has lasted quite well ten years on,so I don't see why it wouldn't last ten more,and the next ten.....
WB is simply spilling out crap simply cos he cant come to grasp with what this network is all about,the more reason he cannot invest in it.
He's simply spreading FUD, I think we can do with paying less attention to him
