There were 3 days in the last week during which suprnova found enough blocks and paid as much as whattomine calculated.
In the last couple of days miners gone from nova so the rest barely find 1-2 blocks per day and profit on it is far less.
Suprnova, however, pays far less on their high performance pools compared to whattomine.

This leaves you two choices: take it or leave it.
Unfortunately there is no other viable option besides mph to mine Zcoin.
You're better off with Zclassic right now.
