WOTG [War Of Tribes] Token

CoinToken.addLiquidity(uint256,uint256) (#832-842) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#834-841)
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.

CoinToken.constructor(string,string,uint256,uint256,uint256,uint256,uint256,address,address,address) (#472-507) performs a multiplication on the result of a division:
-numTokensSellToAddToLiquidity = (_tTotal * 5 / 10000) * 10 ** _decimals (#486)
Consider ordering multiplication before division.
