Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

PurestPonzi.takeFee(address,uint256) (#429-438) performs a multiplication on the result of a division:
-feeAmount = amount.mul(getTotalFee()).div(feeDenominator) (#430)
-burnAmount = feeAmount.mul(burnFee).div(totalFee) (#431)
Consider ordering multiplication before division.

Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.

Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.

Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.

Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.

Contract has 15% buy tax and 20% sell tax.
Taxes are high (over 10%) but contract ownership is renounced.

Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.

Number of Binance Smart Chain (BSC) token holders is low.

Token is deployed only at one blockchain

Token has only one trading pair
