For 3$ only virwox is too expensive i trade sometimes in there, example : i put 60 euro i change eur/ssl -> ssl/btc and i lose about 9 euro !!
But i can sell it for you 3$ is not a big risk
Oh, I see. I wasn't sure what OP meant with 3$. You're right, you need to spend a good amount of money for VirWox to be worth it.
