ADAcash Token

ADAcash.addLiquidity(uint256,uint256) (adacash.sol#449-464) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (adacash.sol#455-462)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.

Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.

Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.

Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.

Token is deployed only at one blockchain

Contract has 15% buy tax and 16% sell tax.
Taxes are high (over 10%) but contract ownership is renounced.

Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.
