You could also install solar panels which comes cheap these days and get the electricity you need for free during the day while relying on the grid at night. Another approach you could take is look for cheap electricity near to where you live. I've seen cases where people deal with electricity generators to buy excess electricity for cheap. The generators like hydro, wind can't sell more than what is on their contract so they sell the excess electricity for cheap.
Thanks for the input! I’m actually based in Europe and currently managing 10 machines. The main challenge for me is the maintenance and setup—it takes up a lot of my time, and to be honest, the noise has been a bit much. Plus, my work requires frequent travel, so it’s hard to stay on top of everything.
I’ve been debating whether to sell the machines and invest in coins to hold, or continue mining but move everything to a third-party hosting service, which would mean shipping my equipment.
Your suggestion about solar panels is interesting, though I’m not sure how feasible that would be given my current setup and lifestyle. The idea of buying excess electricity directly from generators is also appealing, but it might be difficult to organize with the amount of travel I do.
