BBTRX.addLiquidity(uint256,uint256) (#1594-1609) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1600-1607)
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.


Combination 2: Unchecked transfer + 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.

- TRXRewardsFee.add(liquidityFee).add(marketingFee)
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

TRXDividendTracker.getAccount(address) (#1683-1726) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#1723-1725)
TRXDividendTracker.canAutoClaim(uint256) (#1747-1753) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1748)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1752)
Avoid relying on block.timestamp.
