Mycoin.swapAndCharge(uint256) (Eileen gu.sol#491-505) sends eth to arbitrary user
Dangerous calls:
- (success) = address(bnbPoolAddress).call{value: newBalance - bnbForLiquid}() (Eileen gu.sol#502)
Mycoin.addLiquidity(uint256,uint256) (Eileen gu.sol#522-537) sends eth to arbitrary user
Dangerous calls:
- (success) = address(bnbPoolAddress).call{value: balance}() (Eileen gu.sol#534)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Mycoin.swapAndCharge(uint256) (Eileen gu.sol#491-505) uses a dangerous strict equality:
- require(bool,string)(success == true,Transfer failed.) (Eileen gu.sol#503)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

Contract ticker (Eileen gu) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Mycoin.swapAndCharge(uint256) (Eileen gu.sol#491-505) performs a multiplication on the result of a division:
-liquidBalance = tokenBalance * _liquidityFee / (_liquidityFee + _BNBFee) / 2 (Eileen gu.sol#494)
-bnbForLiquid = newBalance * liquidBalance / tokenBalance (Eileen gu.sol#499)
Consider ordering multiplication before division.

Mycoin.addLiquidity(uint256,uint256) (Eileen gu.sol#522-537) ignores return value by pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (Eileen gu.sol#524-531)
