I found a solution to avoid ban. But it's risky and requires careful attention on your coin & cash balance.
You need to find the memory address of your coins using iGameGods overlay. Now either lock the balance to a lower number like 50k or something, or you need to edit it after everywhile when coin balance crosses 200k.
This is kinda annoying because you need to find the coin memory address and edit/lock it everytime you open the game. Also make sure to reduce coin number bellow 100k before saving / closing the game. The game checks for cheating when opening it.
@Puddin can you find a better solution please? Also if you could mod the latest version of FCM 25. Thanks a lot!
