Thanks for sharing this topic! As someone with some experience in the mining industry, I would like to share some practical observations for 2025:
Mining is still profitable at present, but the threshold has indeed increased. The key is to have competitive electricity costs and efficient equipment.
In terms of recommended equipment, Antminer S21 XP HYD (473TH/s) and S21 eXP HYD (430 TH/s) are currently the top choices, but the investment is not small.
An important factor that is often overlooked is the cooling system. The heat generated by high-performance ASICs is huge, and traditional air cooling is no longer enough. We recently started using liquid cooling solutions, and the effect is very obvious - not only does it reduce operating temperatures, but it also significantly improves equipment stability and lifespan.
If anyone is interested in professional liquid cooling solutions, you can visit

In general, mining in 2025 requires a more professional approach and better infrastructure investment, but it is still feasible under the right conditions.
