Thank you for your answer :)) Do you know if I can run out of Gas when I reduce the balance of many customers? Should I store the balances of the user in MapMapper?
Yes you can run out of gas :)
Only if you want to iterate over them, but I would guess it would make more sense to have a usermapper, which will store a unique id for each user and then use the id to access the balance. That way you have an easier time with paginating your call ?
