Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
Contract ownership is not renounced (belongs to a wallet)

Ownable.unlock() (#184-189) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#186)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#89-95):
- (success) = recipient.call{value: amount}() (#93)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#115-132):
- (success,returndata) = target.call{value: weiValue}(data) (#118)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
