MoonTrustToken.setTaxMultiplicator(uint256) (#905-911) contains a tautology or contradiction:
- require(bool,string)((value >= 0 && value <= 200),Tax multiplicator must be between 0 and 200) (#906-909)
Fix the incorrect comparison by changing the value type or the comparison.

Contract ownership is not renounced (belongs to a wallet)

MoonTrustToken.getPoolShare(address) (#789-802) performs a multiplication on the result of a division:
-sharePercent = (baseBalance.mul(ACCURACY)).div(totalSupply()) (#800)
-(poolBalance.mul(sharePercent)).div(ACCURACY) (#801)
MoonTrustToken.getPoolTransferShare(address,uint256) (#804-821) performs a multiplication on the result of a division:
-sharePercent = (transferAmount.mul(ACCURACY)).div(senderBalance) (#819)
-(senderPoolShare.mul(sharePercent)).div(ACCURACY) (#820)
MoonTrustToken.calculateTax(uint256) (#913-922) performs a multiplication on the result of a division:
-taxPercentage = (baseTax.mul(_taxMultiplicator)).div(100) (#918)
-tax = (value.mul(taxPercentage)).div(100) (#919)
Consider ordering multiplication before division.
