report
Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

ERC20.transferToken(address,uint256,address) (#979-988) ignores return value by IERC20(coinAddress).transfer(to,value) (#987)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)

Reentrancy in Token.constructor() (#1401-1411):
External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (#1407-1408)
State variables written after the call(s):
- uniswapV2Router = _uniswapV2Router (#1410)
