Okay great thanks guys for the responses. So would you say kano pays better than pools like antpool, slushpool, and f2pool on average with just one S9?
Yes, two reasons.
Kano shares the transaction fees received when a block is mined as well as the 12.5 bitcoins . This results in blocks with values between 12.5 to 16.5 bitcoins.
Secondly Kano charges a smaller fee, .9%, on the miners earnings.
All of the large pools keep the transaction fees. Slush and Kano, both medium sized pools, share the transaction fees with their miners. Some smaller pools share transaction fees, some don't.
The only pseudo drawback to Kano is that it sometimes goes a day or almost two without hitting a block. That can be discouraging if you are a newbie. Kano also splits the payouts so they are about 20% of value earned divvied up over 5 payments. This is done to smooth out payments even if the input of blocks is very irregular. It means you will receive smaller more numerous payouts untill you have been mining for about 4 or 5 days. After that ramp up time you will receive numerous full payouts. My current payout with two S9s is a bit over .005 per payout. What varies is the number of these payouts I see per day. If averages hold that would mean I will receive .013 bitcoin or better per day for 2 S9s.
I added the second S9 less than a month ago so I can not give you hard figures yet.
Kano pool requires a bit more patience due to the 20% payout system and its some what irregular block find timing. I would strongly recommend committing to Kano pool for no less than 2 weeks and then you will see for yourself how much more you are receiving compared to other pools.
