BinanceDoge.transferEthOut(uint256,uint256) (#1024-1027) sends eth to arbitrary user
Dangerous calls:
- _marketingWallet.transfer(marketingBalance) (#1026)
BinanceDoge.swapETHForTokens(uint256) (#1029-1044) sends eth to arbitrary user
Dangerous calls:
- dexRouter.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,burnAddress,block.timestamp.add(300)) (#1036-1041)
BinanceDoge.addLiquidity(uint256,uint256) (#1064-1077) sends eth to arbitrary user
Dangerous calls:
- dexRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAddress,block.timestamp) (#1069-1076)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BinanceDoge.numTokensSellToAddToLiquidity (#661) is set pre-construction with a non-constant function or state variable:
- (_tTotal * percentToSell) / 10000
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>=0.8.0<0.9.0 (#26) 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) (#300-306):
- (success) = recipient.call{value: amount}() (#304)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#326-347):
- (success,returndata) = target.call{value: weiValue}(data) (#330)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
