How bad does the luck have to be to payout worse than Slush if they had 100% luck?
That is actually very good question. Slush, at the starting of the year is paying 0,01 BTC per week for 1 x 8TH/s miner. So, 1 month -> 0,04 BTC.
I might be wrong (others can correct me) but I think is a 100% luck or kinda...
What kind of bad luck needs to have Kano Poll for paying less than that? can somebody make the calculation?
