1- Loop on the dynamic variable (low severity).

If the user gets more parallel deposits his withdrawal transaction going to cost more transaction fee, because the loop on the dynamic variable is used in the ‘withdraw’ function.

In case of exceeding the GAS limit of the size of transaction withdraw is not possible.
