You can see your current Membership points on the Membership page in the Cash tab:
On this page you will see:
Your points earned this month
Your progress toward the next Membership level
Note: Membership points reset at the beginning of every calendar month, so the page shows your points for the current month rather than a total accumulated over time.
However, you can retain your tier for a year by upgrading to either Luxe or Pinnacle here: https://www.ether.fi/app/cash/membership/compare
