ISC [Issa Coin] Token

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

Contract ownership is not renounced (belongs to a wallet)

CoinHodlCoin._beforeTokenTransfer(address,address,uint256) (contracts/CoinHodlCoin.sol#29-37) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(timeLimit(from) >= 172800,Hodl period is not reached, wait pls.) (contracts/CoinHodlCoin.sol#34)
Avoid relying on block.timestamp.
