hmm.. i don't know but im 99% sure that the hack he used only changed the numbers not for real so if he had 2000 and changed them to 6000 and buy a gun for 5000 he can't buy it because he only have 2000..
And he bought all the gunz when he had a lot of money
dinar hack is vussual,that means you can see the money,but you cant buy anything whit the money
