DogeMetaverse.addLiquidity(uint256,uint256) (#1775-1789) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,marketingWallet,block.timestamp) (#1781-1788)
DogeMetaverse.buyBackAndBurn(uint256) (#1791-1812) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,marketingWallet,block.timestamp.add(300)) (#1800-1805)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DogeMetaverse.rand() (#1624-1640) uses a dangerous strict equality:
- randNumber == 0 (#1634)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

Contract locking ether found:
Contract DogeDividendTracker (#1874-2089) has payable functions:
- DividendPayingToken.receive() (#551-552)
- DividendPayingToken.distributeDividends() (#567-578)
- IDividendPayingToken.distributeDividends() (#460)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

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.
