I agree with the store of value proposition for Bitcoin. At least Buffet has some logic behind is reasoning, however Gold has reached critical mass, Bitcoin has not hence the opportunity.

As for Gates, I think there is something more nefarious going on. It wasn't too long ago he was in favour of cryptocurrencies, now all of a sudden he is sprouting this FUD? His statement is total BS, you mean to tell me one of the richest, well-connected men in the world doesn't have the resources to find a way to short Bitcoin within a few days? I very much doubt that. He could have easily just said he doesn't think bitcoin has any value but the fact he said he would short it was too maximise the fallout in my opinion.
