Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

RichTokenCover.mint(address,uint256) (#1415-1448) contains a tautology or contradiction:
- 0 <= _richFarm.recharge && _richFarm.recharge < tax (#1425)
Fix the incorrect comparison by changing the value type or the comparison.
