Reentrancy in Cakenomics.claimBTC(address) (#1101-1135):
External calls:
- _pancakeRouter.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,addr,block.timestamp) (#1127-1131)
State variables written after the call(s):
- _isWithdrawing = false (#1134)
Apply the check-effects-interactions pattern.

Cakenomics.TeamReduceRewards() (#1421-1431) ignores return value by liquidityToken.transfer(Marketing,amount) (#1429)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Additional information: link

Cakenomics.claimBTC(address) (#1101-1135) uses a dangerous strict equality:
- amount == 0 (#1118)
Don't use strict equality to determine if an account has enough Ether or tokens.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Cakenomics.TeamApproveReduction(bool) (#1433-1462) ignores return value by _pancakeRouter.removeLiquidityETHSupportingFeeOnTransferTokens(address(this),amount,0,0,address(this),block.timestamp) (#1446-1453)
Ensure that all the return values of the function calls are used.

Rename the local variables that shadow another component.

Cakenomics.TeamUpdateLimits(uint256,uint256) (#1374-1391) should emit an event for:
- balanceLimit = newBalanceLimit (#1389)

Emit an event for critical parameter changes.

Cakenomics.TeamRemoveRemainingBNB() (#1464-1469) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= _liquidityUnlockTime,Not yet unlocked) (#1465)
Avoid relying on block.timestamp.

Cakenomics.sellLimit (#793) is set pre-construction with a non-constant function or state variable:
- _circulatingSupply
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.

solc-0.8.4 is not recommended for deployment
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.

Low level call in Cakenomics.TeamRemoveRemainingBNB() (#1464-1469):
- (sent) = Marketing.call{value: (address(this).balance)}() (#1467)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

TeamRemoveRemainingBNB() should be declared external:
- Cakenomics.TeamRemoveRemainingBNB() (#1464-1469)
