Who gives a fuck what Draper, Mcafee, Buffet, etc etc etc say will happen? bitcoin is way bigger than any of these clowns. Their opinions aren't any more valid than mine or yours.
What they say matters man, and they have really tried for bitcoin in their own little way by creating awareness for it and strengthening the market through their word of encouragement in form of positive prediction, seems you forgot so soon that crypto market is a speculative ones, and these figures you discarded shabbily like that have their fans who believes in them and would take whatever they say to them.
Aside their fans, there are people that will deem fit to believe what they believe also, so it is good that they are speculating the way they are doing, at least, they are not creating some sort of FUD news, if they don’t speculate, they would give chance too FUD news and I must tell you that bitcoin really do respond to these things a lot.
