zclmine.pro is junk. Share response time is measured on avg at 15 seconds last night, causing lots of rejected shares and eventual client disconnection. Now I've got ZCL sitting with them that I can't get out due to a high min payout, as others are complaining about.
I'll withdraw my negative comments here if they transfer my earnings to me, but pretty sure that isn't going to happen.
Don't use the zclmine.pro mining pool.
They are definitively scammy, you can see blocks on the explorer that do not appear on the pool. Yesterday I mined 10% of what I should have...
