Complexity

This contract is a fork of DINO BUSD with a jackpot feature.

ReentrancyGuard is not necessary as ERC20 tokens are not vulnerable to reentrancy attacks since it doesn’t call any external addresses: it’s not possible to create a recursive loop. This adds unnecessary gas to transactions.

Team Trust

The team has 100 members in their telegram group at the time of the audit and does not seem to be their first project. They claim to have launched several tokens in the past.

Other Risk

Jackpot amount should be using SafeMath instead of raw operations.

Depositors are either investing max (15000 BUSD) to enter as jackpot’s last winner or are becoming candidates - investing max takes over candidates.
