lol good luck man. You won't ever see those Bitcoins again. Chances are they MAY stat issuing refunds in a few years, and the Price per bitcoin may sky rocket then and at that point, they won't even think to refund you.
This is pretty interesting. And it's really funny how these hackers think they are hard asses but back down when the tables are turned on them. 20K in Bitcoin is a hefty sum to bring the guy back to his senses and make him back down.
Just want to inform you at most will get 300 USD for this account. A buyer will not play all these games you are counting the value for. Games like Rush Bros, for example. No one has heard of it yet it is counting towards the retail price. Now take this example and apply it to the other various games no one has heard of nor will play.
