GDoge [Gangster Doge Inu] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

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

GangsterCatInu.TOTAL_SUPPLY (GangsterDogeInu.sol#20) should be constant
Add the constant attributes to state variables that never change.

GangsterCatInu._transfer(address,address,uint256) (GangsterDogeInu.sol#60-85) performs a multiplication on the result of a division:
-_fee = amount.div(100).mul(transferFeeRate) (GangsterDogeInu.sol#79)
Consider ordering multiplication before division.
