again, not too sure. When I did it, it was something like this.
Bought - $7.5 USD
Realised I couldn't withdraw USD.
Sold BTC in AUD
You can ask the tech support at Tradehill. I know Mt.Gox allows for withdrawl of USD into any account for a flat fee of $10 i think it was?
hmmm two problems with this... 1) converting back through btc is going to net me less coins than i had originally, and 2) the aud market has hardly any volume.
i'm thinking about the possibility of just withdrawing the USD to paxum, and then have paxum send it to my bank account... reading their site now.
