I am a fan of Warren Buffett and he has a very logical investment philosophy and I understand his statements on CNBC News. Warren Buffett always relies on something that is really valuable and understands how a company works to invest. But for Bitcoin, it uses the money of an investor for some unclear purpose. That is for Warren very hated. I think that his opinion is correct to say that the Crypto market is not considered as investment. We can only do speculation in the Crypto market to make a profit.
