Mining Climate Rating (MCR)
A single-number snapshot of how favorable current conditions are for Bitcoin miners.
Purpose
The Mining Climate Rating condenses the two most important on-chain variables — BTC price and network difficulty — into a 0–100 score that tells you at a glance whether it's a good time to be mining Bitcoin.
Think of it like a weather forecast for miners: a high score means sunny skies (strong revenue per terahash), while a low score means stormy conditions (revenue is compressed).
Inputs Used
- BTC Price (PBTC) — The current USD price of Bitcoin, sourced from CoinGecko.
- Network Difficulty (D) — The current mining difficulty, sourced from blockchain.info. Difficulty adjusts roughly every two weeks and determines how much hashing power is required to mine a block.
Both values are refreshed every 6 hours.
Formula
We first compute a revenue ratio R:
R captures how much revenue one terahash of mining power earns relative to the difficulty it faces. When price rises or difficulty drops, R goes up.
The base MCR score is then:
The square root compresses extreme values so the score stays in a readable range. The result is clamped to 0–100.
Interpretation Bands
70–100 · Favorable
Strong revenue environment. Mining is broadly profitable across most hardware and electricity scenarios.
40–69 · Moderate
Viable for efficient operators but margins are thinner. Electricity cost matters more.
0–39 · Challenging
Revenue is well below normal. Marginal miners are likely unprofitable and may begin shutting off.
What This Is / What This Is Not
✓ What MCR is
- A quick health-check of mining conditions
- Based on verifiable on-chain data
- Useful for comparing today vs. historical norms
- Updated every 6 hours automatically
✗ What MCR is not
- A prediction of future BTC price or difficulty
- A substitute for a full financial model
- Personalized to your electricity cost or hardware
- Investment or financial advice of any kind
Data Update Cadence
MCR is recomputed every 6 hours (4× daily). Each snapshot is stored in our timeseries database, allowing you to view historical trends over 7, 30, 90 days or the full available history.
