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 ?
It's not the fear that's stupid.
:-D
You can actually check, since the ADDRESS of your paper wallet is PUBLIC, you can very well see that the coins arrived therein.
Only the PRIVATE KEY is, well, "private". This is the part you need to ACCESS your coins.
