If bitcoin's price reaches $ 50,000, I think his hatred will increase.
It's all about incentives. Bitcoin doesn't need to prove itself, because it did already. These investors aren't stupid, they have seen Bitcoin grow from nothing to something, don't let the mainstream media distract you too much.
As always, if you don't see value in something, you ignore it and for that reason won't continuously spend time talking it down. If you see high level investors keep talking trash about Bitcoin, there very likely is an incentive that motivates them to do that. I don't say they are buying into Bitcoin or plan to do so, but when these entities keep talking trash, it's actually a bullish signal, and a very big one. Something is happening in the background, whatever it may be.
Jamie Dimon got busted already, and I wouldn't be surprised to see Warren Buffett eventually follow the same route. There are millions and even billions to be made here, what bank or investor doesn't want to ride this out?
By the way, it turned out that he had a bitcoin investment, if I remember correctly. So we shouldn't take this guy too seriously.
I think you're referring to Bill Gates. Warren Buffett as far as I know never owned anything.
