I have some ex-banker /Wall Street friends. One is loving the challenge to the current money/government system. He's all for this and blockchain....the otheres are leary of these systems. I just think that like China, if they can't really get control over it, they will outlaw them due to some regulatory reason, or there will be a collapse and people will demand safeguards. There are competing cryptocurrencies as well, so that should be interesting to see the positioning. You already see sites accepting Bitcoin, right alongside of Paypal or credit cards.
