So many unknowns, so much is un-knowable.
- I was in your exact position earlier this year. I had rented 1000 Square feet in Texas, and had 100KW of 3-phase power available immediately and plans for more.
- As crypto dropped, I abandoned my plans, started selling my gear (still have a bunch) and shut down the facility.
- I am converting cash into crypto rather than rent, and mining at home only, using only Z9-mini's. All GPUs are shut down, and all S9's are shut down.

So what do we know?
- Hash rate of every worthwhile coin is the one thing that is actually mooning.
- Bitmain prices their products for ~1 year ROI, maybe a bit less. In my experience, Antminer S-series will pay back 1X in a year, and never pay another 1X because of hashrate growth.
- Rising value of Crypto to Fiat, makes all of the above math look better than if it stays flat.
- Of course something new is coming from Bitmain. S9 series is more than 2 years old. It's time.

What can we do?
- Assume crypto is going to moon. Buy Crypto because you can't mine crypto as fast as you can buy crypto.
- Assume crypto will drop. Sell what you have and be done with it.
- Assume crypto will be flat. Maybe mine if your costs are low enough, but need to recognize that you're in a declining return over time because of hashrate growth.

What should you do? Be careful. Even at 5.5 cents/kWh, be aware you're competing with people in China and other parts of the world who are paying much less or even not paying for their power.

This is the best advice so far in my opinion, this person knows what is the right thing to do in most cases, merit deserved.
