Tell me about that : I have some Bitcoin on my mtgox.com wallet, and I would like to transfer them on another wallet, and especially a paper wallet that I've never added to any wallet client, I generated it with bitaddress.org
And the fact that I actually can't see my balance, can't check if my Bitcoins have arrived in my new wallet, well this is why my bitcoins are still in mtgox.com wallet ^^
So, is this a stupid fear, am I the only one ?
