Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

RedFeg.sendETHToFee(uint256) (#430-433) sends eth to arbitrary user
Dangerous calls:
- _FeeAddress.transfer(amount.div(2)) (#431)
- _marketingWalletAddress.transfer(amount.div(2)) (#432)
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.

Contract ticker (REDFEG 🦍) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

RedFeg.openTrading() (#435-460) ignores return value by uniswapV2Router.addLiquidityETH{value: address(this).balance}(address(this),balanceOf(address(this)),0,0,owner(),block.timestamp) (#444-451)
RedFeg.openTrading() (#435-460) ignores return value by IERC20(uniswapV2Pair).approve(address(uniswapV2Router),type()(uint256).max) (#456-459)
Ensure that all the return values of the function calls are used.

RedFeg._transfer(address,address,uint256) (#368-414) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.

RedFeg._previousTaxFee (#231) is set pre-construction with a non-constant function or state variable:
- _taxFee
RedFeg._previousteamFee (#232) is set pre-construction with a non-constant function or state variable:
- _teamFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
