[Big Jerms]

Okay im semi new to this whole hacking thing and ive recently been addicted to this game called crime city created by gree and i downloaded blue stacks so i can play to accounts. I tried hacking it found the address changed the value but every time i try to use the money i hacked it just goes away and its not useable. Does anyone know how to successfully hack that game and actually be able to use the money or is it simply just not possible cause ive read other forums about it and said it was impossible basically?
