What's wrong with aikapool? 3btcz in 10 hours with over 100h/s?? really?? the worst pool i've ever seen.
Yea they have 50% hidden fee. I had the same experience with mining VOT in two separate occasions. They pay out about 50% of what you mine.
I just use SuprNova their hidden fee seems to be around 10% or less. Most pool are running 30-35% hidden fee.
Ragnar pool is seems a good pool. Have you ever had a bad experience?
