Yes, even I came to hear about this recently, and we can understand that it all depends on one's personal belief and approach whether he wants to take part in the cryptocurrency trading or not. Even when a few months back when China bans on ICO and at that time JP Morgan used to say that It's a fraud and now just before two days he says that he was Wrong. I don't think their statements or discussion will affect the bitcoin prices or their trend, so just chill out mate. I knew about Warren Buffet and some his principles as he never invests where there is lack of fundamentals or where he doesn't understand the Cryptocurrency and Blockchain technology in-depth.
