I've just started to mine IntenseCoin from 6th jan.. last two days some mining pools were down for a day.. Before that i mined 100 ITNS per day.. right now estimation output is around 30 to 40 ITNS
Most likely the increased network hashrate that is coming from Nicehash or a Farm. When it happens the difficulty rockets and your income drops. Been happening 24/7 recently, they dip in when the difficulty drops and out when it rockets.
I don't know? Every single pool i look up. Is showing like 700+ workers.... every single one.... In early Dec the pools i was using only had like 10 and 25 .......those pools both now are 900+. I think there just really are alot of miners not just nice hash...
