I haven't heard any references to Reptilian overlords from @dollarvigilante, although I am less than convinced cryptos have any potential to overthrow the world order. However, they may well provide a basis for a new economic structure if they are filling a vacuum, or merely one leg of a multi-pronged strategy.
Jeff doesn't just talk about cryptocurrencies, he talks about all kinds of conspiracy theory shit such as the moon landings being faked, CIA controlling peoples minds, etc. I like Jeff as I find him amusing and entertaining but rational wouldn't be a word I'd use to describe him.
