MagicDOGE.getHolderSellFactor(address) (#1601-1617) uses a dangerous strict equality:
- _holderLastSellDate[holder] == 0 (#1606)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

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.

MagicDOGE._transfer(address,address,uint256) (#1769-1898) performs a multiplication on the result of a division:
-otherSellFee = amount.mul(liquidityFee).div(100).mul(getHolderSellFactor(from)).div(100) (#1872)
Consider ordering multiplication before division.

MagicDOGE._transfer(address,address,uint256).lastProcessedIndex (#1892) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

MagicDOGE.addLiquidity(uint256,uint256) (#1978-1993) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1984-1991)
Ensure that all the return values of the function calls are used.

Variable 'MagicDOGE._transfer(address,address,uint256).iterations (#1892)' in MagicDOGE._transfer(address,address,uint256) (#1769-1898) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1893)
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.

MagicDOGEDividendTracker.canAutoClaim(uint256) (#2216-2222) uses timestamp for comparisons

Avoid relying on block.timestamp.
