Contract ownership is not renounced (belongs to a wallet)

Context._msgData() (@openzeppelin/contracts/utils/Context.sol#20-22) is never used and should be removed
Remove unused functions.

CoinracerToken.allowance(address,address).owner (contracts/CoinracerToken.sol#101) shadows:
- Ownable.owner() (@openzeppelin/contracts/access/Ownable.sol#34-36) (function)
CoinracerToken._approve(address,address,uint256).owner (contracts/CoinracerToken.sol#288) shadows:
- Ownable.owner() (@openzeppelin/contracts/access/Ownable.sol#34-36) (function)
Rename the local variables that shadow another component.

CoinracerToken._transfer(address,address,uint256) (contracts/CoinracerToken.sol#227-251) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(whitelist[sender] == true || block.timestamp - lastTrans[sender] > 10,ERC20: anti-bot sender) (contracts/CoinracerToken.sol#234)
- require(bool,string)(whitelist[recipient] == true || block.timestamp - lastTrans[recipient] > 10,ERC20: anti-bot recipient) (contracts/CoinracerToken.sol#235)
Avoid relying on block.timestamp.

Additional information: link

CoinracerToken._transfer(address,address,uint256) (contracts/CoinracerToken.sol#227-251) compares to a boolean constant:
-require(bool,string)(whitelist[sender] == true || block.timestamp - lastTrans[sender] > 10,ERC20: anti-bot sender) (contracts/CoinracerToken.sol#234)
CoinracerToken._transfer(address,address,uint256) (contracts/CoinracerToken.sol#227-251) compares to a boolean constant:
-require(bool,string)(whitelist[recipient] == true || block.timestamp - lastTrans[recipient] > 10,ERC20: anti-bot recipient) (contracts/CoinracerToken.sol#235)
Remove the equality to the boolean constant.
