Bengals.transferEthOut(uint256,uint256) (#1012-1015) sends eth to arbitrary user
Dangerous calls:
- _marketingWallet.transfer(marketingBalance) (#1014)
Bengals.swapETHForTokens(uint256) (#1017-1032) sends eth to arbitrary user
Dangerous calls:
- dexRouter.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,burnAddress,block.timestamp.add(300)) (#1024-1029)
Bengals.addLiquidity(uint256,uint256) (#1052-1065) sends eth to arbitrary user
Dangerous calls:
- dexRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAddress,block.timestamp) (#1057-1064)
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.

Pragma version>=0.8.0<0.9.0 (#14) is too complex
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 Address.sendValue(address,uint256) (#288-294):

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#314-335):
- (success,returndata) = target.call{value: weiValue}(data) (#318)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
