What's the turn around time between receiving crypto currency and getting that into e.g. USD in a bank for you? As long as that is short, volatility is minimized. I think the volatility issue is a major pain-point to people though. As long as you keep your money liquid in cryptocurrency, isn't it essentially holding stock (albeit driven by BTC mining and transactions) in terms of capital gains and losses? But if you use stock, I believe you are required to hold it for periods by the SEC (don't quote me, but, blah blah Holding Period?), so maybe crypto wins in this regard anyway...
