People far overestimate the ability to pick tops and bottoms. I am better than most, because at least my trading is profitable. Still I typically only capture 30% of the full extent of a move, such as $100 per coin on average if the move was from 700->400.
Good for you that your trading is profitable, I know you took some serious losses to MtGox/sturles but atleast you didn't loose everything.
My Feb was actually positive despite of it, cause I nailed the 400 dip. You should care about sturles, because he is the one who must have got hit with his beloved exchange..:/
