I still remember him way back 2017 when I was starting to learn Bitcoin. He's the exact same person that also said at that time that "Bitcoin is a fraud".
It's not only him that's against Bitcoin at that time, but there are many more, mostly rich people that are related or at least owns a bank. Where are they now? They can't defend their stance towards Bitcoin? They rather choose to remain silent than defending what they think about Bitcoin. As for Dimon, TBH, I don't care about what he's saying towards Bitcoin, and I don't think many here cares about his statements towards it. At the end of the day, Bitcoin will thrive despite the anti-Bitcoins out there.
Peter Schiff, Jamie Dimon, Warren Buffet and even both Biden and Trump at some point. These are just the few rich businessmen that are against Bitcoin back then, and now we aren't hearing anything from them, and some even supports Bitcoin already... or are they. Hmmm.
