Speculation in the value of cryptocurrency has forced the market into a regime of operation where neither the constraints of power & compute nor supply of semiconductors apply right now. The hierarchy of value constraints goes something like:

Speculation > silicon constrained mining > power & capital constrained mining

I believe the silicon constraints would instantly relax as soon as speculation falls into line based on how much hardware everyone has been stacking up on lately.

At the end of they day, the cost of energy & your ability to keep the machines operational will be the final constraint. This is the one that the long investors should anticipate. I.e. "How do I mitigate power cost in a power-cost-constrained market".

Right now at current market prices, owning an entire power plant to run your operation is folly. In a few more years when a delta of 2c/KWh is make-or-break on profitability, it makes perfect sense.
