AstroDogeRising.buyBackAndBurn(uint256) (#1801-1822) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,marketingWallet,block.timestamp.add(300)) (#1810-1815)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

AstroDogeRising.rand() (#1637-1653) uses a dangerous strict equality:
- randNumber == 0 (#1647)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract locking ether found:
Contract CakeDividendTracker (#1883-2099) has payable functions:
- DividendPayingToken.receive() (#577-578)
- DividendPayingToken.distributeDividends() (#593-604)
- IDividendPayingToken.distributeDividends() (#488)
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.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

Not a direct threat, but may indicate unreliable intentions of developer. Both name and ticker of current token are widespread, i.e. common across multiple tokens. This is slightly suspicious

AstroDogeRising._transfer(address,address,uint256) (#1666-1767) performs a multiplication on the result of a division:
-swapAndSendCakeDividends(sellTokens.div(10 ** 2).mul(rand())) (#1729)
Consider ordering multiplication before division.

Variable 'AstroDogeRising._transfer(address,address,uint256).lastProcessedIndex (#1759)' in AstroDogeRising._transfer(address,address,uint256) (#1666-1767) potentially used before declaration: ProcessedCakeDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1760)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
