Metanftworld.addLiquidity(uint256,uint256) (#1714-1729) sends eth to arbitrary user
Dangerous calls:

Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Metanftworld._transfer(address,address,uint256) (#1517-1603) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (#1576)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (#1580)
Consider ordering multiplication before division.

BNBDividendTracker.getAccount(address) (#1806-1849) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#1846-1848)
BNBDividendTracker.canAutoClaim(uint256) (#1870-1876) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1871)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1875)
Avoid relying on block.timestamp.
