Reentrancy in CoinToken.constructor(string,string,uint256,uint256,uint256,uint256,address,address,address) (#303-317):
External calls:
- success = service.call.value(msg.value)() (#314)
Event emitted after the call(s):
- Transfer(address(0),tokenOwner,totalSupply) (#316)
Apply the check-effects-interactions pattern.

Ownable.unlock() (#75-80) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked Time is not up) (#77)
Avoid relying on block.timestamp.

StandardToken.transfer(address,uint256) (#162-189) compares to a boolean constant:
-require(bool)(tokenBlacklist[_to] == false) (#164)
StandardToken.transfer(address,uint256) (#162-189) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#163)
StandardToken.transferFrom(address,address,uint256) (#196-223) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#197)
StandardToken.transferFrom(address,address,uint256) (#196-223) compares to a boolean constant:
-require(bool)(tokenBlacklist[_from] == false) (#198)
StandardToken.transferFrom(address,address,uint256) (#196-223) compares to a boolean constant:
-require(bool)(tokenBlacklist[_to] == false) (#199)
Remove the equality to the boolean constant.

SafeMath.mul(uint256,uint256) (#10-17) is never used and should be removed
Remove unused functions.

Pragma version^0.4.24 (#7) allows old versions
solc-0.4.24 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.

Low level call in CoinToken.constructor(string,string,uint256,uint256,uint256,uint256,address,address,address) (#303-317):
- success = service.call.value(msg.value)() (#314)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
