ChinuDoge.addLiquidity(uint256,uint256) (#1151-1161) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityAddress,block.timestamp) (#1153-1160)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

ChinuDoge.earlyBuyPenaltyEnd (#660) is never initialized. It is used in:
- ChinuDoge._transfer(address,address,uint256) (#987-1101)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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 (Chinu Doge) 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.

ChinuDoge.slitherConstructorVariables() (#597-1548) uses literals with too many digits:

ChinuDoge._transfer(address,address,uint256) (#987-1101) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(! boughtEarly[from] || earlyBuyPenaltyEnd <= block.timestamp,Snipers can't transfer tokens to sell cheaper until penalty timeframe is over. DM a Mod.) (#1092)
Avoid relying on block.timestamp.

Pragma version0.8.9 (#7) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
