My bid which is the highest (2BTC for 25H/s) is the closest to Genesis-Minings.
Genesis mining has 25H/s for 6500USD or 10.604BTC for 1 year so 2.651BTC for 3 months
Zeropond has 50H/s for 14.516BTC for 6 months so for 25H/s divide 14.51/2/2 so 3.629 for 3 months
25H/s 3 Months
My Bid = 2 BTC
Genesis Mining = 2.651BTC
Zeropond = 3.629
The other bids are kind of throwing shit at a wall and see if it sticks IMHO
