TheCycle.clearStuckBalance(uint256) (#256-269) uses a dangerous strict equality:
- success == true (#263)
TheCycle.swapTokens(uint256) (#350-372) uses a dangerous strict equality:
- temp == false (#364)
Don't use strict equality to determine if an account has enough Ether or tokens.

TheCycle.modifyTaxes(uint256,uint256) (#279-292) contains a tautology or contradiction:
- require(bool,string)(0 <= _liquidityFee && _liquidityFee <= 10,Requested liquidity fee not within acceptable range, [0,10] .) (#280-281)
TheCycle.modifyTaxes(uint256,uint256) (#279-292) contains a tautology or contradiction:
- require(bool,string)(0 <= _marketingDevRewardsFee && _marketingDevRewardsFee <= 10,Requested marketing/dev./rewards fee percentage not within acceptable range, [0,10].) (#282-283)
Fix the incorrect comparison by changing the value type or the comparison.

TheCycle.swapTokens(uint256) (#350-372) performs a multiplication on the result of a division:
-halfLPTokens = LPtokens / 2 (#352)
-BNBForLP = newBalance * halfLPTokens / swapAmount (#360)
TheCycle.swapTokens(uint256) (#350-372) performs a multiplication on the result of a division:
-marketingDevRewardsTokens = tokens * marketingDevRewardsFee / totalFees (#353)
-BNBForMarketingDevRewards = newBalance * marketingDevRewardsTokens / swapAmount (#361)
Consider ordering multiplication before division.

TheCycle.addLiquidity(uint256,uint256) (#392-405) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,autoLiquidityReceiver,block.timestamp) (#397-404)
Ensure that all the return values of the function calls are used.

TheCycle.changeFeeReceivers(address,address)._autoLiquidityReceiver (#294) lacks a zero-check on :
- autoLiquidityReceiver = _autoLiquidityReceiver (#296)
Check that the address is not zero.

TheCycle.clearStuckBalance(uint256) (#256-269) compares to a boolean constant:
-success == true (#263)
TheCycle.swapTokens(uint256) (#350-372) compares to a boolean constant:

Remove the equality to the boolean constant.

ERC20._burn(address,uint256) (#128-136) is never used and should be removed
Remove unused functions.

Additional information: link

TheCycle.totalFees (#203) is set pre-construction with a non-constant function or state variable:
- marketingDevRewardsFee + liquidityFee
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.

Pragma version=0.8.13 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.13 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.

- (success) = address(marketingDevRewardsReceiver).call{gas: 30000,value: amountBNB}() (#261)
Low level call in TheCycle.swapTokens(uint256) (#350-372):

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
