CORAL [CORAL COIN] Token

CORAL.recoverERC20(address,uint256) (#615-617) ignores return value by IERC20(tokenAddress).transfer(owner(),tokenAmount) (#616)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

CORAL.airdrop(address) (#583-596) sends eth to arbitrary user
Dangerous calls:
- address(uint160(_refer)).transfer(referEth) (#592)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract creator or owner is blacklisted for past scams

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Combination 2: Unchecked transfer + 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 ownership is not renounced (belongs to a wallet)

CORAL.extractBNB()._owner (#620) shadows:
- CORAL._owner (#282) (state variable)
Rename the local variables that shadow another component.

solc-0.6.8 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.
