Token._transfer(address,address,uint256) (#1029-1097) uses a dangerous strict equality:
- tradingActiveBlock == block.number && (automatedMarketMakerPairs[to] || automatedMarketMakerPairs[from]) (#1074)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

Token._transfer(address,address,uint256) (#1029-1097) performs a multiplication on the result of a division:

-tokensForMarketing += fees * buyMarketingFee / buyTotalFees (#1086)

Pragma version^0.8.9 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
