- Rank by daily net profit at your real electricity rate, not raw hashrate - efficiency decides ROI.
- Factor in NEXA network difficulty trend and expected price volatility when estimating payback.
- Check stock status: in-stock miners ship in 1-3 business days; back-ordered units take 2-4 weeks.
- Ask about hosting if home electricity is above $0.08/kWh - managed hosting often flips marginal miners back into profit.

What is the best NEXA miner to buy?
The best NEXA miner depends on your electricity rate. The table above sorts every NEXA-capable ASIC by live daily net profit - the top row is currently the most profitable choice given your rate input.
Is NEXA mining still profitable?
NEXA mining profitability varies with coin price, network difficulty, and your electricity cost. Use the live ranking plus your own electricity rate to see the current net profit for each miner before you buy.
