BetWC._transfer(address,address,uint256) (contracts/BetWC.sol#159-201) performs a multiplication on the result of a division:
-totalTaxAmount = (amount * _totalTax) / denominator (contracts/BetWC.sol#179)
-insuranceTaxAmount = (totalTaxAmount * insuranceTax) / _totalTax (contracts/BetWC.sol#180-181)
BetWC._transfer(address,address,uint256) (contracts/BetWC.sol#159-201) performs a multiplication on the result of a division:
-totalTaxAmount = (amount * _totalTax) / denominator (contracts/BetWC.sol#179)

Consider ordering multiplication before division.
