The wallet provides the instantaneous POW difficulty. WhatToMine shows the average POW difficulty (24-hr, 3-day, 7-day) but it has been broken and hasn't updated for a couple of days. Is there another site or some other way to see the average POW difficulty?
my pool
https://cryptohub.online/pools/ has a log of difficulity, checking it once per hour. If you use its calculator it will show you possible profit based on average difficulity for last 24 hours.
I will think to add special page to show average difficulities
very convenient pool for both beginners and old people, add referral links to attract, good luck
