Not sure I understand this fully.
Is it impossible to withdraw Bitcoins from MtGox to another exchange?
It seems weird that the price is dumping.
The basic gist is that most investors believe Gox is going to go bankrupt and it's better to have a claim against them in fiat than in btc -- so people are dumping all they can, and at this point, at whatever price they can get.
I see...
But the reasoning behind this must be that there actually exists fiat at MtGox, either already in ppl accounts or somehow deposited.
They are as many buyers as sellers, so it seems a bit strange that one part wants to have fiat, while another want Bitcoins, if investors are going to claim against them?
