Sorry for the broken responses. I have done some trading and done decently, not a big fan though. Obviously they can fluctuate wildly very quickly for seemingly no reason, and I can't stay up all night to watch the charts since they are 24x7.
That said, trading crpypts is not like a company/stock, its more like hedging one currency against another.
I am mostly buy and hold. Adding on the dips. Just keeping my position, if it goes to 0 then cool -- I can afford to lose it -- if it goes up like I think it will then great, I am a very happy camper!
