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.
Have already read this article before on reddit and i was just wondering why he sounds like that where in fact he owned thousands of bitcoin. So ironic to think the richest man invest on bitcoin and oppose on it too.
