So I don't have a bone in BTCST or any of the bets around it, but I have a bit of time and a little bit of a mathematics background (undergrad degree in math), and am really curious to figure out exactly how many BTC were invested with pirateat40... has anyone linked (or could anyone share) the transactions of their investments with him?

I heard the claim that he's the owner of the largest bitcoin account account [1]. Does anyone know of evidence to support it?
