- What is hashprice?
- Hashprice is the daily revenue generated per unit of hashing power, expressed in USD per petahash per day (USD/PH/day). It combines the current Bitcoin price, network hashrate, and block reward into a single number. When hashprice is high, mining is more profitable; when it falls — due to a Bitcoin price drop or rising difficulty — margins compress. It is the most important real-time indicator of Bitcoin mining economics.
- How is Bitcoin mining revenue calculated?
- A miner's daily gross revenue equals its hashrate (in PH/s) multiplied by the current hashprice (USD/PH/day). Monthly gross revenue is daily revenue × 30.4. To get net profit, subtract the electricity cost: power (kW) × 24 hours × 30.4 days × your electricity rate ($/kWh). The gross margin is net profit divided by gross revenue.
- What does revenue per kWh mean for Bitcoin mining?
- Revenue per kWh is the gross mining revenue generated per kilowatt-hour of electricity consumed, calculated using the most efficient Bitcoin miner available at each point in time. It cuts through Bitcoin price noise: if your electricity costs $0.07/kWh and revenue per kWh is $0.13, your gross margin is $0.06/kWh — regardless of whether Bitcoin is at $50,000 or $150,000. It shows at a glance whether the current market justifies operating at your electricity rate.
- What is Bitcoin network hashrate?
- Network hashrate is the total combined computing power of all Bitcoin miners worldwide, measured in exahashes per second (EH/s). As it grows, each individual miner earns a smaller share of the block reward. The Terminal displays a 14-day moving average to smooth short-term variance from measurement noise and pool luck.
- What is Bitcoin mining difficulty?
- Bitcoin's mining difficulty is an automatically adjusting parameter that controls how hard it is to find a valid block. It recalibrates every ~2,016 blocks (roughly two weeks) to keep the average block time near 10 minutes. When more hashrate joins the network, difficulty increases; when miners leave, it decreases. Difficulty is shown in trillions (T).
- How often is the Terminal data updated?
- Current metrics — hashprice, Bitcoin price, network hashrate, and difficulty — are fetched live and cached for 10 minutes. Historical chart data is updated once per day. Bitcoin price history is sourced from CoinGecko; hashrate, difficulty, and fee data from mempool.space.
- What is the difference between hashprice and mining profitability?
- Hashprice is a market-wide indicator: it measures gross revenue per unit of hashrate before electricity costs. Profitability depends on your specific electricity rate. If hashprice is $0.12/kWh equivalent and you pay $0.07/kWh, your gross margin is roughly 42%. Mining is profitable when your electricity cost is below the revenue per kWh the market is generating.
- What Bitcoin mining hardware is most efficient in 2025?
- The most efficient Bitcoin miners available in 2025 are Bitmain Antminer S21 series machines, achieving efficiencies below 15 J/TH. The Antminer S21 Pro and S21 XP consume around 5 kW while delivering 200–300 TH/s. Hydro-cooled variants like the S21 Hydro push efficiency further. Efficiency is critical: a 1 J/TH improvement at scale saves thousands of dollars per month in electricity.
