The main feature of crypto currencies is their anonymity. I don't think this is a good thing. The Governments ability to find money laundering and tax evasion and terrorist funding is a good thing. Right now crypto currencies are used for buying fentanyl and other drugs so it is a rare technology that has caused deaths in a fairly direct way. I think the speculative wave around ICOs and crypto currencies is super risky for those who go long.
I can't say he is not right, but the crypto as a whole, it's going to be embraced by the world. Governments are ruled by men, and we the people make the rules. Cryptos are here to stay!
