Token is either risky or in presale. For presale 30+ is a fine score.


Contract ownership is semi-renounced (passed to a contract)

MetaMine.releaseIthInvestorTokens(uint8) (#682-697) performs a multiplication on the result of a division:
-numVestingPeriodsPassed = now.sub(vestibleTokens[index].vestingStartTime).div(vestibleTokens[index].vestingTimeUnit) (#686)
-unlockedTokens = numVestingPeriodsPassed.mul(tokensPerVesting) (#687)
Consider ordering multiplication before division.

MetaMine.allowance(address,address).owner (#458) shadows:
- Ownable.owner() (#297-299) (function)
MetaMine._approve(address,address,uint256).owner (#614) shadows:
- Ownable.owner() (#297-299) (function)
Rename the local variables that shadow another component.

MetaMine.releaseIthInvestorTokens(uint8) (#682-697) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(vestibleTokens[index].supplyLeftToVest >= tokensPerVesting,Not enough to vest) (#684)
- require(bool,string)(unlockedTokens > vestibleTokens[index].supplyVested,Not enough unlocked) (#688)
- require(bool,string)(vestibleTokens[index].supplyVested.div(tokensPerVesting) < vestibleTokens[index].numVestingPeriods,Cannot vest more than numVestingPeriods) (#689)
MetaMine.pegOut(uint256,string) (#702-706) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(value < _balances[msg.sender],Cannot peg out more than owner amount) (#703)
Avoid relying on block.timestamp.
