9th/s is decent, when market swings I'll be pushing my s7 again pool side. Personally I mine for power independence. I feel utilities and expenditures are what taxes should go towards (IMO not MFB). Other wise a 2pac is is great for this pool. I hope every person is a hobby miner at some point plus manufactures market towards large scale farming, making a relateable asic meaningful and well thought out. Mining a small hash rate isn't a novelty and never will be.
I just added an old ebit E9 6.5T miner to the solo pool. I underclocked it to the minimum of 400M. It's pulling 600W at the wall and hashing at just under 4TH. It's costing me $1.15/day to run at my power rate.
A $1.15/day is a great price to pay to get a small chance to find a block, and make use of a "defunct" miner. If you run your S7 you can underclock it to get a savings on power but still have lots more hashing power than stick miners. I would test it first at the minimum frequency and see how many watts it's pulling vs hashrate.
