Coinhunters token is a highly rewarding liquidity protocol built on the Binance Smart Chain. Coinhunters’ token symbol is $CHTR. We are launching Coinhunters to ensure that the community is rewarded well for its holding power. Apart from its rewards distribution mechanism, we will also put a marketing wallet to ensure that publicity is sufficient enough to populate the moon.
Coinhunters token is backed by coinhunters.cc, a website well known for its comprehensiveness regarding crypto projects. This website is particularly worth mentioning because it is the top crypto voting platform worldwide. Coinhunters will be a huge project in rewarding tokens because of its frequently visited website, tokenomics, and marketing plans.
Coinhunters.addLiquidity(uint256,uint256) (#1679-1694) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1685-1692)
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.

Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
