High ISSUE

The system used is called ROI and must be considered 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Users' principal deposits cannot be withdrawn, users can get dividends and referral commission.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).

  • Level 2:          2.5%
  • Level 3:          0.5%
