I trade at another exchange that's inside the SEPA zone, has a 6x lower fee, and doesn't require ridiculous amounts of papers to verify yourself (which is illegal to request without a permit from the Dutch CBP, but I can hardly object because then I simply can't transfer fiat currency out of gox). The trading lag was also much lower there.
But are the other markets as rabid as MtGox? I think that is why alot of people even put up with the higher fees.
Also when MtGox comes back online in ~3 hours I believe we will be in for some more bot action manipulation, especially with the temporary fee waive now.
