Optimization suggestions

 

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

If the user gets more parallel deposits his withdraw 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 TRON limit of the size of transaction withdraw is not possible.

Note:

This comment is relevant only if a user creates an excessive amount of parallel deposits (more than 100).
