The last time I calculated the capitulating price for miners in post halving, it was at 37000$.
I am a Bitcoin mining expert and consultant and regarding my experience, the least energy price in the market is around 2.5 $cent/kwh (Which is quite rare!). so the minimum price typically starts from 3 $cent upto 4.5 $cent for industrial mining. (and 5$cent for smaller ones)... You whether need to buy in-scale capacity of electricty from power plant companies (50 MW or above) or you should be smart enough in finding intact/virgin places with cheap energy resources that are not affordable to be utilized in normal consitions!
The normal energy price for Bitcoin mining is sth in the range of 3-5 $cent....In the non-US countries, ususally the cheap source of energy is from Hydro plants...However, middle east is going to be a new player especially UAE! They can break the prices in below 3$cent
