I’ve been researching Bitcoin mining hardware and trying to figure out the best setup for long-term profitability, but I’m feeling stuck on a few key aspects.
First, with the rapid advancements in mining technology, how do I determine which Bitcoin mining hardware will remain viable for at least the next few years? Some models seem to offer high hash rates but consume a lot of power, while others are more energy-efficient but may become obsolete faster.
Second, when comparing ASIC miners, how do I accurately assess cost versus performance? I see that some machines have a lower upfront price, but their energy efficiency is poor, which might lead to higher electricity costs over time. Is it better to invest in premium Bitcoin mining hardware with better efficiency or opt for a lower-cost machine with the possibility of upgrading sooner?
Also, regarding heat management and maintenance, how can I ensure the longevity of my mining setup? Do certain brands or models have better durability, and how often should I expect to replace components?
Finally, with the mining difficulty increasing, is it still profitable to buy new Bitcoin mining hardware, or is cloud mining a more practical alternative in 2025?
