It looks like Warren Buffet still does not understand Crypto!
I understand that he has a ton of money and that's great but the truth is he built that based off of the old ways of investing and that does not make the results any less valid or anything but there is a real issue with him commenting on CryptoCurrencies without giving any thought to the BlockChains that they originate from.
His claim that Crypto Currencies have no actual value would be pretty accurate if they existed in absence of BlockChains but it is the BlockChains themselves that bring the value.
his argument against CryptoCurrencies is actually the argument most Goldmoney types use against Fiat Currency. The irony is likely lost on him.
