PoorDoge is a Meme token created by the Anonymous for the poor. PoorDoge has dynamic buying and selling tax rates, dynamic buying rewards, holding PoorDoge to get USDT dividends, the prize pool automatically repurchases and burns tokens, and trading burns tokens (transfer will not burn tokens), these complex mechanisms are designed to protect diamond hands and poor investors.

PoordogeCoin.getBasePriceNow() (#1728-1753) uses a dangerous strict equality:
- currentTimeMin == lastTimeMin (#1734)
Don't use strict equality to determine if an account has enough Ether or tokens.

PoordogeCoin.getLpPriceNow() (#1755-1781) performs a multiplication on the result of a division:
-pdPriceInWbnb = uint256(pwreserve0).mul(priceMagnitude).div(uint256(pwreserve1)).div(10 ** 9) (#1766)
-wbnbPriceInUsdt = uint256(uwreserve0).mul(priceMagnitude).div(uint256(uwreserve1)) (#1778)
-pdPriceInWbnb.mul(wbnbPriceInUsdt).div(priceMagnitude) (#1780)
Consider ordering multiplication before division.

PoordogeCoin._transfer(address,address,uint256).lastProcessedIndex (#1487) 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.

Variable 'PoordogeCoin._transfer(address,address,uint256).claims (#1487)' in PoordogeCoin._transfer(address,address,uint256) (#1425-1492) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1488)
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.
