Force Withdrawal Backdoor (critical, high severity)

Based on the force withdrawal rules which return 80% and max referral commission 20%, the owner has the privilege of depositing and using force withdrawal 100% of the deposit will return and earning 10% profit because of the owner fee. Only the owner can withdraw the contract balance. Users should participate in the project if they trust the owner.

 

High ISSUE (high, medium severity)

The system used is called ROI and must be considered as HIGH-RISK.

Users' principal deposits cannot be withdrawn, users can get dividends and referral commission. Dividends are paid from deposits of other users. Do always invest with proper knowledge and investigation.
 

Optimization suggestions

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 exceeding the GAS limit of the size of the transaction, withdrawal is not possible.

Note:

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