BME [BitcoMine] Token

BME.addLiquidity(uint256,uint256) (BME Contract.sol#464-479) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,Lwallet,block.timestamp) (BME Contract.sol#470-477)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Variable 'BME._transfer(address,address,uint256).claims (BME Contract.sol#382)' in BME._transfer(address,address,uint256) (BME Contract.sol#271-385) potentially used before declaration: ProcessedBTCDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (BME Contract.sol#383)
