After the BTC Halving, Which Mining Rig Still Stays On? Better Options Than the Bitmain Antminer S21 Pro?

In May 2024, Bitcoin experienced extreme volatility, briefly plunging below the $60,000 threshold to $59,685 before rebounding strongly above $65,000.

Yet even amidst these turbulent market conditions, the Antminer S21 Pro delivered consistent returns to miners thanks to its unparalleled energy efficiency.

Now, in 2025, Bitcoin faces new cycles of volatility. Will history repeat itself? With waves of next-gen miners flooding the market, does the S21 Pro still hold its competitive edge? The evidence speaks clearly: Having weathered multiple market cycles, this mining powerhouse remains the intelligent choice for reliable profitability.
