BTC CASH Token

SmartContract.airdrop(address) (#444-454) sends eth to arbitrary user
Dangerous calls:
- address(uint160(_refer)).transfer(referEth) (#451)
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...)

Contract ownership is not renounced (belongs to a wallet)

SmartContract.clearETH()._owner (#368) shadows:
- SmartContract._owner (#159) (state variable)
Rename the local variables that shadow another component.
