I disagree on the bubble comment. Rightfully so only of the two camps will eventually be right as to the current potential state of bubble. Splitting the difference between the two opinions because the two sides felt strongly about it is the age old centrist trap that gets us nowhere.

As for the end of bitcoin/cryptos - I hope not. A bursting of this bubble is hopefully just a rite of passage so that they can mature and gain adoption. Basically everyone knows what they are now.
