Hope y'all are being facetious...'cuz I was... Undecided

Anyway...I've got enough data now to figure how things are going to look, at least for me. I've got three S7s in Labrador that are running at a 50% overhead, including power and psu's, based on the pool's production since the halving. Those particular units were ROI already, so that's a moot question in this instance. An S9 would run at the same absolute overhead as an S7, but produces around 12THs, v. 4THs. The math isn't complicated. It will make money on a monthly basis, as do the S7s.

The problem, of course, is in the ROI. Until Bitmain gets the cost down on the S9, I'm looking at running A6s instead. If I ran an S9 at the datacentre, it would take (given spot staying stable) around ten months for ROI.

Am I missing something in my math? S9s run ~$2000. 13T/s gets you ~.003/block. That's ~1000 blocks for roi. Where do you get your 10 months from?

she may have extrapolated 10 months based on those 2 stats. it is reasonable to think it could be 10 months

Just thought I missed something. Though if we would start hitting 10+ blocks a day regularly it could be done in ~4 months. That would be great. Let's see some bright bright green!
