Bitcoin On-Chain Metrics — NVT, Hash Rate, Miner Revenue

What does Bitcoin On-Chain Metrics do?

Bitcoin on-chain metrics provides a comprehensive valuation and network health snapshot in a single Apify run. It fetches the NVT ratio (Network Value to Transactions), daily transaction count and volume, BTC UTXO analytics-adjacent miner economics, hash rate in EH/s, mining difficulty, the next difficulty retarget countdown, and mempool fee recommendations — combining data from blockchain.info, mempool.space, and CoinGecko into one clean record. No API key is required. Apify handles scheduling, retries, and cloud execution so you get reliable on-chain data tracker output without running your own infrastructure.

Why use Bitcoin On-Chain Metrics?

The on-chain data tracker gives researchers, traders, and developers a structured data pipeline into Bitcoin's fundamental health. Here is why teams choose this actor:

• Valuation screening: The NVT ratio acts as a "P/E ratio for Bitcoin." Use it to flag when BTC is overvalued (NVT > 100) or deeply undervalued (NVT < 20) relative to actual economic throughput.
• Mining profitability monitoring: Track real-time miner revenue in USD, fee pressure ratio, and hash rate trends to anticipate miner selling pressure or capitulation events.
• Fee market analysis: Mempool fee recommendations (fastest/30-min/1-hour) feed directly into wallet applications, DeFi bots, or transaction scheduling tools.
• Difficulty retarget alerts: Know exactly how many blocks and estimated hours remain until the next adjustment — critical for hashrate economics models.
• Research and backtesting: Schedule hourly or daily runs to build a time-series on-chain dataset without managing multiple API connections.

How to use Bitcoin On-Chain Metrics

1. Open the actor on Apify Store and click Try for free.
2. No configuration is required — the default run fetches the full on-chain snapshot.
3. Click Save & Run. The actor completes in under 20 seconds.
4. Access the single output record in the Dataset tab (JSON or CSV export available).
5. Use the Apify Scheduler to run daily or hourly and build a historical on-chain database automatically.

Data fields

Field	Description
btc_price_usd	Current BTC price in USD (CoinGecko)
market_cap_usd	Bitcoin total market capitalization
tx_count_24h	Number of confirmed transactions in the past 24 hours
tx_volume_btc	Total on-chain transaction volume in BTC
tx_volume_usd	Total on-chain transaction volume in USD
nvt_ratio	NVT ratio = Market Cap / Daily TX Volume (USD)
nvt_signal	Valuation signal: undervalued (<20), fair (20-50), elevated (50-100), overvalued (>100)
hash_rate_eh	Current network hash rate in exahashes per second
difficulty	Current mining difficulty value
blocks_until_retarget	Blocks remaining until next difficulty adjustment
hours_until_retarget	Estimated hours until next difficulty retarget
miner_revenue_btc	Total miner revenue (subsidy + fees) in BTC over the last 24h
miner_revenue_usd	Total miner revenue in USD
total_fees_btc	Transaction fees paid to miners in BTC
fee_pressure_ratio_pct	Fees as a percentage of total miner revenue
fee_fastest_sat_vb	Mempool fee for next-block confirmation (sat/vByte)
fee_30min_sat_vb	Fee for ~30-minute confirmation
fee_1hr_sat_vb	Fee for ~1-hour confirmation
fetched_at	UTC timestamp of the snapshot

Cost estimation

Pricing is $0.005 flat per run (Pay-Per-Event, one event per successful snapshot).

Schedule	Runs per month	Monthly cost
Once per day	30	$0.15
Every 6 hours	120	$0.60
Every hour	720	$3.60

Even hourly on-chain monitoring costs under $4/month — far cheaper than a dedicated blockchain node or premium data subscription.

FAQ

Does this actor require a blockchain node or API key? No. Data is sourced from blockchain.info, mempool.space, and CoinGecko's public APIs. No accounts, API keys, or subscriptions are required.

What does the NVT signal mean in practice? The NVT ratio compares Bitcoin's market cap to the actual economic value being transacted on-chain. When NVT is below 20, the network is moving a large volume of value relative to its market cap — historically associated with undervalued periods. NVT above 100 indicates the price may be running ahead of on-chain utility, a historically elevated zone.

How does this differ from Bitcoin Miner Revenue Tracker? Bitcoin On-Chain Metrics focuses on the full network health picture — NVT valuation, fee market, and retarget timing alongside miner economics. The BTC Miner Revenue Tracker actor focuses specifically on the block-by-block breakdown of subsidy vs fee revenue and the fee dependency trend over the past 7 days.
