/*
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
