 TOKEN HIGHTLIGHT
  - No mint function
  - No one can't change the taxes (3.5% for buy and 3.5% for sell = total 7%)
  - Taxes automatically transfer to DEAD wallet
  - More you buy or sell, less total supply of token
  - 100% of token is added to LP
  - 100% of initial LP is locked
  - Renounce Ownership (Dead wallet is owner)
  - Max per wallet as 2.7% of initial total supply (2.7% of 7,777,777 tokens)

  All above mentioned you can check it in the verified code
