 Buy tax:
     Tax is the same no matter the time:
         9% to the house wallet
 Sell tax:
     If selling within 3 days:
         9% sent to the house wallet
         9% sent to the burn wallet
     If selling within 3-6 days:
         9% sent to the house wallet
         6% sent to the burn wallet
     If selling within 6-9 days:
         9% sent to the house wallet
         3% sent the burn wallet
     If selling after 9 days:
         9% sent to the house wallet
