I roi'd my s9 shares already. How did I do that?
The day of this announcement. I put .47btc into my wallet I grabbed 9750 shares of s7 at .00004821
I waited a couple of days and used earnings to push me to 10000 shares of s7.
and 10 shares of s9 I listed the 10000 shares of s7 at 0.00005400 sold it and was at about .538 in my wallet from .47 and 10 shares of s9.
I sent the .47 back to my own wallet and had .068 btc I grabbed 390 shares of s9
So I have 400 free gh of s9.
I will keep rolling it over see what it grows to.
I used to do that back when Hashnest still had the S3, S5, and S4- the different prices were great for trading back and forth, and the chat in the hashnest app was actually used quite a lot. Things have gotten much quieter since then and profit is harder to come by sadly

That was not so long ago. I think there is still a lot of good fun to be had doing this. It's the best thing going that I am aware of.
