120 blocks , 1 block is 1 confirmation.
With that speed of 4 blocks per day will take ages?!
Is there a better pool ? maybe
https://zcoin.miningpoolhub.com ? I see that they are able to find 10 blocks per hour which is way better than suprnova.
4 blocks not by 1 pool, 120 blocks by all network . it takes about 15-18 hours
