Presumably somewhere in the ballpark of $2M worth.

If that was correct, every miner would have to win every block to stay in business. That's clearly not the case.

To my understanding that'd be true if the energy cost was $2M per miner, but I think jpcfl was suggesting $2M total. i.e. that an individual miner would spend $100 on energy for a $100 expected return, which may be a 10% chance at $1000 or a 100% chance at $100.

Could adjust $2M up slightly for whatever portion was done by crypto-mining malware or dabblers with higher expected energy costs than return, and down for the portion done by professional miners who will be expecting a slightly positive return even after factoring in other costs.

If I spend $2M to mine $2M of gold, and the value of that gold increases by 2x over the next 10 years, then I think I could stay in business. That would actually be a pretty solid business.

The value of BTC has increased nearly ~200x in the last 10 years. I don't anticipate it will do this again, but I'm sure some of these miners think it will continue to grow at some rate (plus, they have already capitalized on the last 10yrs of growth).

Sorry, that isn't how proof of work mining works. The key point to understand is the effect of difficulty on mining.

Well, 2M of energy + opex at least
