I'm a semi-big fan of cryptocurrencies and I've swallowed a sip of the koolaid. Still, it's a bit of a stretch to call them "investment banking." The various DAOs have delivered mixed results. It's hard enough to write bug-free code in regular life. Imagine trying to write a bug-free digital contract that will be immortalized forever on the blockchain.

So no. It's not investment banking. Maybe it's the beginnings of a payments network.
