Token seems to be a scam (type: phishing / airdrop scam).

Contract creator or owner is blacklisted for past scams

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

DECAO.airdrop(address) (#448-458) sends eth to arbitrary user
Dangerous calls:
- address(uint160(_refer)).transfer(referEth) (#455)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

Pragma version0.6.8 (#13) allows old versions
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.
