I think it's this. The price just went up too damn fast... Gox is still having withdrawal "problems" (denials is a better word).
CampBX is pretty good too, for me: I just withdrew a few hundred dollars yesterday at ~2 and it got here today.
Hm yes. They have some legal problems with CoinLab (we all remember the sueing that goes back and forth), they seem to have missing licences, they seem to have problems with US authorities (locked down accounts) etc. Whatever. At least an official statement would be nice.
At the current situation, storing EUR or $ on emptygox accounts is a big risk. Same for all other exchanges that are lacking legal alignments, such as bitstamp (as far as i could see they do not seem to have legal alignment). Even Coinbase does not seem to be a trustworthy alternative for the storing as bitcoins, this would require a working SMS Gateway...
