No problem man glad to help you out, well game will ban you if you change the value of coins above 1000, coins are easy to edit just search for the value of the coins shown at your main screen, play a level and complete it, then refine your search, you would be left with 2 - 5 results change the value to your desired amount and your are done. If it does not display the change the press the level button and then close the level and see. If still no change, then, close and restart game.

I suggest you to freeze the coins value at 500 and then spend it or just keep it till 500. Also let me know what is your game type by going to your data/app/lib folder. Since there are 4 types (depending on your device) x86, x86_x64, arm and arm64.
