Token.startTime (#1034) is never initialized. It is used in:

Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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.

Contract ownership is not renounced (belongs to a wallet)

Token._transfer(address,address,uint256) (#1120-1166) performs a multiplication on the result of a division:
-swapAndLiquifyV1(haveAmount.div(5).mul(4)) (#1144)
Token._transfer(address,address,uint256) (#1120-1166) performs a multiplication on the result of a division:
-amount = amount.div(100).mul(90) (#1158)
Token._splitOtherToken() (#1227-1274) performs a multiplication on the result of a division:
-thisAmount = thisAmount.div(5).mul(3) (#1231)

Token._splitOtherToken() (#1227-1274) performs a multiplication on the result of a division:
