I bought these cd-keys when prices were lower than 2 euros. Now I'm willing to make some profit as Kinguin's prices has gone up to 3 euros. I would need at least full name and Steam account's email address and maybe also access to that email address, if I would be interested to steal ones Steam account. But I'm just trying to make business here.
Yea, it's Altcoin Agent who's misunderstanding that, he thought you were selling a steam account which you could later contact steam support and claim it was stolen. Steam returns the account and you keep the
BTC.
But you not selling an account you are selling the CD key so all the buyer has to do is open steam and click
Game -> Activate a product/game on Steam
and enter the code to receive the game. No risk of any accounts being lost.
