WTF [White Tigger Finance] Token

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

WhiteTiggerFinance._transferFrom(address,address,uint256) (#473-527) uses a dangerous strict equality:
- sender != pair && block.number == lastBuyBlock[sender] (#482)
WhiteTiggerFinance.rebase(uint256,int256) (#603-638) uses a dangerous strict equality:
- epoch == 0 (#605)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

WhiteTiggerFinance.manage_blacklist(address[],bool).i (#681) 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.

WhiteTiggerFinance.rebase_percentage(uint256,bool) (#851-859) performs a multiplication on the result of a division:
-newSupply = rebase(0,int256(_totalSupply / (1000000000) * (_percentage_base1000)) * (- 1)) (#854)
Consider ordering multiplication before division.
