What conditions are needed for profitable production?
And, do you know what place is best for all these items? Space!
1. Cheap electricity (preferably free). according to rough estimates, mining leaves of 1100 MW or 9636 GW⋅h (0,829, MTA) per year.
2. In space, low temperatures, which greatly facilitates the cooling of the system.
3. There is a lot of space and there are no taxes and rules yet.
And test this idea is not so difficult. It is enough to take a small mining farm to the ISS and see what happens. And in the distant future, perhaps, they will build entire orbital cities for mining.
How about that?
Do you think it can be implemented in the near future?
