I've been talking to a lot of Bitcoin miners recently, and a few main topics keep coming up—ROI, energy efficiency, hardware lifespan, and electricity costs. It seems like everyone has their own view on what’s most important for running a good mining operation. For someone new to Bitcoin mining, I’m curious: what do you think matters the most? Is it getting the best ROI, using energy efficiently to save money, keeping equipment costs low, or making sure your hardware lasts a long time? How do you balance these things when deciding what hardware to buy or which mining approach to take? There are so many factors, and it can be hard to know where to begin as a beginner. Any advice or tips from experienced miners on what to focus on first and what to avoid would be really helpful.
