I've been wondering whether pirate is involved as well. The one confusion is that he mentions local customers, and if he's doing bitcoin HFT to profit off of volatility (thus smoothing it out) then I don't understand why he would have local customers... but this is probably explainable.

The only thing that would affect my profits would be a huge spike in price over a very short period of time.
That is consistent with what we have been talking about. A spike would break through a ceiling or floor he had set up.
