High ISSUE

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Users' principal deposits cannot be withdrawn, users can get dividends and referral commission.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).

Withdraw Rules

on each withdrawal, 10% of dividends will be deducted and remain in the contract and  90% of dividends transfer to the user’s wallet.

 

Referral System (Match Bonus)

The contract pays a 9% referral commission over 3 levels

  • Level 1:          5%
  • Level 2:          3%
  • Level 3:          1%

Notes:

  • Referral should be an active user; it means the referral address has at least one deposit
  • The referrer is specified once at the time of the first deposit and is assigned to the user without the possibility of changing. From each subsequent Deposit, the referrer will get his percentage.
