I think Loaded is at it
Exceeded $40m in bids on MtGox briefly, which just seems amazing to me for a couple reasons. (1) Why is so much money still flowing to MtGox where prices are higher and the ability to withdraw USD is practically non-existent. (2) I remember when the entire bitcoin "market cap" was a fraction of what's currently visible in bids just on Gox. Surely there's quite a bit more money not presenting itself on the order book, plus all the money sitting on all the other exchanges.
Right now i use Gox, primarily because it was the first exchange I used. I have no interest in getting my cash out, so the withdraw problems do not bother me and frankly i consider them temporary. Can Gox shut down and take my money, yes, but I could say the same for any exchange.
In the future the withdraw problems will sort themselves out, or it wont matter because i can survive with bitcoin alone and getting BTC out of Gox is a snap.
I am completely in Fiat on Gox as I am sure a lot of people are. Everyone wants more coins and this current point in BTC history seems to be an opportunity to wait and get back in with more coins then when I got out.
BTW, I use several other exchanges but none for USD. Whether it makes a difference or not I feel better knowing Gox is higher for USD. Certainly, my fiat balance is quite a bit higher in Gox than it would be elsewhere, my hope is that the dips when I buy back will have a smaller spread than other exchanges when I pull the trigger.
That is how i am playing it.
