That being said, one question I still don't have the answer on is... how the heck do you get money taken OUT of MtGox? So, someone could buy some BTC from Coinbase right now for $98.86 and have them in their account immediately (presuming they are fully approved). They send them to MtGox and sell them for $106.10. That leaves a gross profit of $7.24. Subtracting out the 1% fee from Coinbase leaves a theoretical profit of $6.26 per BTC meaning you could make $313 per day.
So, how the heck do you get money back out of MtGox? Do you have to wait for them to issue a check or something like that? Still, you'd think that if you had enough $ in your account, you could do this for awhile.
What's the catch?
it only shows how hard (time consuming) is it to move money from bitcoin exchanges. You have to wait weeks to get your international bank wire transfer from MtGox
