Contract ownership is not renounced (belongs to a wallet)

USTC._rTotal (#416) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
USTC._previousTaxFee (#434) is set pre-construction with a non-constant function or state variable:
- _taxFee
USTC._previousLiquidityFee (#437) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Not a direct threat, but may indicate unreliable intentions of developer. Both name and ticker of current token are widespread, i.e. common across multiple tokens. This is slightly suspicious
