Invest? I think investing in crypto is purely based on greater fool theory. Doesn't mean there aren't any legitimate uses for cryptocurrency, let alone the blockchain technology. In this sense, why should Coinbase and a currency exchange booth in some airport be considered any different? Of course, Coinbase doesn't quite operate statelessly like that, and to me that's the issue here.
