While the cryptocurrency conversation online is dominated by right-libertarians, I think you'll find that a lot of hard/radical leftwing direct-action types are very much obsessed with cryptocurrency and structures like the DAO. I personally don't look at the cryptocurrency scene/DAO with anything more than bemusement, but I think that community is often presented in a very unpleasant light (look at the weird nerds!).

A more charitable stereotype might be that cryptocurrencies and automated contracts appeal to anyone who thinks that they can design (through their technical expertise) a better world than the current political elites. I'm not saying that they're right or that their line of thought hasn't been historically responsible for atrocities, but I don't think it's fair to paint them as sociopaths.
