What is the best ASIC for mining Bitcoin in 2025? The complete guide from Minent.fr
The Bitcoin mining market is evolving rapidly: every year, new, more powerful and efficient models appear. By 2025, choosing the right one will be crucial. ASIC SHA-256 It depends primarily on your profile: budget, electricity costs, available space, and noise tolerance. Here's the Minent.fr complete guide to choose the miner that maximizes your profitability.
⚙️ Understand the essential criteria before buying
Before choosing a model, keep four key parameters in mind:
- Hashrate (TH/s) : the computing power of the device. The higher it is, the more blocks you can mine.
- Power consumption (W) : the electrical power required to operate.
- Energy efficiency (J/TH) : the energy required to generate one terahash. This is the ultimate profitability criterion.
- Cooling Whether air, hydro or immersion, it influences the noise, stability and longevity of the equipment.
The right choice is therefore the one that balances power, efficiency and operating cost.
💸 Category 1: Best “medium budget” ASIC (€2,000 – €4,000)
