Brief Description about token, should be appealing: Golden Kitty Cake is inspired from the Waving Lucky Cat from the Chinese/Japanese community. It was believed that the figurine will bring good fortune and luck to the owners. Now, it is Golden Kitty's turn to bring you tons of fortune through its own token and the CAKE token that it is spreading.
Now you get to earn real passive income with meme-tokens. Golden Kitty Cake provides you a real chance to earn CAKE token daily. With our Cake Bank utilities, every GKCAKE transactions shall rewards 7% of CAKE reward into the cake bank. After 24 hours, you get to claim your CAKE token daily. The more GKCAKE you hold, the more CAKE token you’ll earned!
Aside from that GKCAKE also has a security insurance features, when a whale dumps occurs, it will be triggered automatically, to bring back the price.

GoldenKittyCake.addLiquidity(uint256,uint256) (#1212-1225) sends eth to arbitrary user
Dangerous calls:
- router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#1217-1224)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
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.
GoldenKittyCake.collectFee(address,uint256,uint256,bool,bool) (#923-981) performs a multiplication on the result of a division:
-_reflectionBalance[insuranceWallet] = _reflectionBalance[insuranceWallet].add(insuranceFee.mul(rate)) (#972)
-insuranceFee = amount.mul(_insuranceFee[0]).div(10 ** (_feeDecimal + 2)) (#969)
Consider ordering multiplication before division.

Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
