GENKToken.swapAndCharge(uint256) (contracts/GENK.sol#286-300) uses a dangerous strict equality:
- require(bool,string)(success == true,Transfer failed.) (contracts/GENK.sol#298)
Don't use strict equality to determine if an account has enough Ether or tokens.

GENKToken.swapAndCharge(uint256) (contracts/GENK.sol#286-300) performs a multiplication on the result of a division:
-liquidBalance = tokenBalance.mul(_liquidityFee).div(_liquidityFee + _BNBFee).div(2) (contracts/GENK.sol#289)
-bnbForLiquid = newBalance.mul(liquidBalance).div(tokenBalance) (contracts/GENK.sol#294)
Consider ordering multiplication before division.
