CheemsBillionaire.swapBack() (#299-340) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#324)
- (developmentSuccess) = address(developmentFeeReceiver).call{gas: 30000,value: amountBNBdevelopment}() (#326)
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 (CheemsBillionaire) has length of 17 chars.
Not a direct threat, but may indicate unreliable intentions of developer.

CheemsBillionaire.slitherConstructorVariables() (#155-424) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 1000 * 3 (#191)
Consider ordering multiplication before division.

Remove unused functions.

CheemsBillionaire._maxTxAmount (#167) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 1) / 200
CheemsBillionaire._maxWalletSize (#168) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
CheemsBillionaire.swapThreshold (#191) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1000 * 3
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.
