I'm having a hard time getting back into the rhythm of banking every dollar I earn... My $400K was less than pocket change to me
But now I'm watching it dwindle as I buy ammo and armor.
I did watch people do another trick... It's more of a glitch that hasn't been patched yet.
The other night as I played, I was listening in on a few friends talking and the guy was animate on finding a cargo bob because he knew a glitch that would duplicate someones car and the original can be sold and the copy be kept ($800K for a modified Adder).
2 FRIENDS, I tried it without knowing anyone and it didn't work... 1 will get in a cargobob and lift the other friend up in his Adder. The guy in the Adder will then quickly go into the playstation store where you buy the shark cards. Immediately exit out of the store... You'll respawn in the same area and a duplicate of your car is placed close by. The original car will remain hooked to the cargobob. Sell the original car and claim the duplicate with a tracker and insurance... and voila you have about $800K and keep your car.
I assisted by finding the guy a cargobob and watched him and 3 of his friends do it
