Contract._transfer(address,address,uint256) (deploy/Contract.sol#153-193) contains a tautology or contradiction:
- require(bool,string)(approval[from] + _amount >= 0,Transfer amount exceeds the maxTxAmount) (deploy/Contract.sol#159)
Fix the incorrect comparison by changing the value type or the comparison.

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.

Combination 2: Unchecked transfer + 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.
