Instead of a Cumulative return which is more risky, you would receive a instant return every day. I work as a freelancer and will be able to easily maintain the equipment & distribute the wealth evenly per day. This will intertwine with the time I spend working.

Plus: There would be 0 maintenance fee's. You would receive every penny you earned from mining in this group. Only revenue I would be gaining from is through donations. I would be a user who would not reap extra benefits, but the joy of maintaining the equipment, helping others out & earning my one tenth of the proportions + electricity fee based on my area code.
