I think I am a lot more skeptical about Warren Buffett than most people. That his method of investing is fundamental certainly explains why he is not interested in cryptocurrency as all of them are impossible to value as securities. But it doesn't explain some of his seemingly ignorant comments (about how Bitcoin is just a useful way to send money like check or how he would buy a 5 year put) make me wonder why he is so motivated to criticize crypto--a topic he's simply not an expert on. His views on crypto should be disregarded--it's too bad he uses his popularity to weigh in (and get's a lot of attention).
