I don't get it, 61 shares and 60 days = 10 years, so some people will pay now and get the hashpower in 10 years?
Does not make sense.
You should collect all the money, and share it equally from the start between all investors...
i have total 63 Shares.
each of them will be rent for 60days. how you come up with 10 years?
63*60 = 3 780 days. (around 10 years)
That means that the last guy will not have anything before 10 years...
