So much has been talked about regarding the fiat "stuck" in Gox and how people would theoretically have to buy bitcoin to get their currency out. However, the other thing is that who wants to sell their coins there if you can't get the money out? If most people with coins who need the money quicklyever would prefer to use Bitstamp for these obvious reasons, there is just going to be ALOT more bitcoins available on Bitstamp
We are seeing this in the last week. The spread has been over $200 for no particularlya very good reason.
