Frequently Asked Questions
Is Bitcoin mining still profitable?
Yes, but profitability depends on your ASIC efficiency (J/TH), electricity cost, and the current hashprice. Latest-gen ASIC at $0.06/kWh can generate $8-12/day. Use our calculator to check with live data.
How do you calculate mining profitability?
Mining revenue = hashprice × your hashrate. Profit = revenue − electricity cost. The hashprice itself depends on BTC price, network difficulty, block reward, and transaction fees. Our tool calculates this in real-time.
What is Bitcoin hashprice?
Hashprice is the daily revenue in USD per PH/s of computing power. Formula: (Block Reward + TX Fees) × 144 × BTC Price / Network Hashrate. It's the single most important metric for mining profitability.
Which ASIC miner is the most profitable?
In 2026, the most efficient ASIC operate at 10-15 J/TH: Antminer S21 XP, Whatsminer M66S, and Antminer S21+. The best choice depends on your electricity cost. Browse our catalog of 75+ models.
What electricity price do I need to mine profitably?
With a latest-gen ASIC (10-15 J/TH), you can mine profitably up to ~$0.09/kWh at current hashprice. Older ASIC require cheaper power. Use our calculator to find your exact breakeven electricity rate.
What is Bitcoin mining difficulty?
Difficulty is a Bitcoin network parameter that automatically adjusts every 2,016 blocks (~2 weeks) to maintain an average block time of 10 minutes. The more hashrate on the network, the higher the difficulty rises — and the lower the revenue per TH/s. It is the most impactful factor on long-term mining profitability.
How long does it take to get ROI on an ASIC miner?
Payback period depends on the hashprice, your electricity cost, and the machine's purchase price. As a benchmark, an S21 XP at market price with $0.06/kWh electricity can break even in 12-18 months at current hashprice. Our Monte Carlo simulation gives you P10/P50/P90 scenarios to estimate your ROI precisely.
Should I hold or sell my mined Bitcoin?
The optimal strategy depends on your fixed costs and your conviction on Bitcoin's price trajectory. Selling immediately locks in revenue. Holding (HODL) amplifies gains if BTC appreciates, but increases risk. Our calculator supports both strategies: compare P&L in 'immediate sell' vs 'hold' mode over any time period.
