When stuff you have up on the market sells, the money is automatically deposited into the
bank.
Thats probably where it came from.

Its really not all that much i have almost like 100,000k.

I am lev 200 boxer got over 999,00k in bank also got vulcan 999 ammo corpse grinder and
shooter im neva tellin u my username

That is because you are not level 200, you don't have 999k, and your don't have a vulcan.

If your level 200 and have only 999,000 cash then that means your the most broke level 200
ever and if you have a vulcan and only 999 ammo then that means your vulcan is worthless
fell free not to tell us your username because thats the lamest account ever -_-
