- _totalSupply = 150000000 * (10 ** uint256(18)) (PopCoin.sol#21)
Use: Ether suffix, Time suffix, or The scientific notation

Low level call in SafeERC20.callOptionalReturn(IERC20,bytes) (imports.sol#298-309):
- (success,returndata) = address(token).call(data) (imports.sol#302)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
