Im confused cause like i said its been over 10 hours now. I used the address mtgox gave me and its still showing up as unconfirmed in my bitcoin client account. have they gone and eaten my coins?
MtGox requires 6 confirmations. This should happen in about an hour if your transactions gets into the next block after you spend it. If you sent it without a fee, it will likely take longer. You will not see it on MtGox until it has 6 confirmations. You can check
