Bitcoin at all time high

[BetCheckBet]

If mtgox is not holding funds though I'd be curious why they have withdrawal limits... everythign I have read indicates mtgox holds funds

I am confused. So Person A sells 60 bitcoins to Person B for 12,000 usd. Who is paying the 12k to person A. Who pays out the conversion? At the end of the day someone has the real currency

mtgox takes a 0.6% commision. Mtgox allows people to hold two accounts bitcoins and cash. They use this to facilitate the transfer between parties as I understand.
