It might make the most sense to figure out what you could get for the S2 if you sold it today. Use that as a cost figure, and churn the numbers on how long it will take to break-even with 0 running cost.Can you wait that long? Do you want to?
I think continuing to wait for Bitmain, or harping at them is a waste of time. They have forgotten about this months ago.

One thing I could not tell who is in the graphic above? I do agree time to let go.
