Gold is tracked by the server. Gold can not just suddenly appear out of thin air, even if you wanted it to. You can, however, make it appear as though you have alot of gold, but you can do nothing with it. This is what gorgisw is doing. The only way to acquire gold ingame is to either:
1. Earn it yourself.
2. Send a packet to the server, making the server read this peice of information insted of the amount of gold you have. But this is illegal
And I can't help you with illegal things.
Nor do I want to. =P
