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?
square root of the thingy over hash times luck to the difficulty of the network equals you're better off with Kano over time.
