It's the miners in developing countries that have the natural advantage: re #Ethiopia and #hydroelectric, and #Bitcoin goes further there than in developed countries (purchasing power parity). The #halving gets rid of inefficient miners. It also raises the exchange rate for #BTC because miners have to make a profit so the exchange rate (when they sell) has to reflect that. So net-net a gain for developing disadvantaged countries. I would add AI and datacentres will also benefit them as Bitcoin is leading in this area.
