Bitcoin’s Miners’ Position Index has fallen to -1.04, one of the lowest readings in its recorded history. This is only the third time the 30-day moving average has approached the -1 threshold. The MPI measures total miner outflows against a one-year moving average. A low reading means miners are sending dramatically fewer coins to exchanges than their historical behavior would suggest.
Furthermore, on March 18, 2026, the MPI z-score hit -3.19, a record low. This indicates miners are selling at a rate far below historical norms. This does not happen often. When it does, it tends to matter.
Miners represent one of Bitcoin’s most consistent natural sources of selling pressure. They have ongoing operational costs, electricity, hardware, payroll, that historically force regular BTC liquidation regardless of market conditions.
When that flow dries up at this scale, available sell-side supply contracts meaningfully. That contraction does not guarantee price appreciation on its own. However, it creates conditions where demand-side forces face less resistance. One of the market’s most persistent structural headwinds simply stops showing up.
The behavior can reflect two different underlying realities. Miners may be collecting block rewards in anticipation of higher prices. Or they may be unable to sell at current prices without absorbing losses, a condition that signals compressed margins rather than confidence.
At this scale, inactivity can reflect miners unable or unwilling to sell. This is in contrast to miners confidently holding in anticipation of gains.
CryptoQuant analyst RugaResearch notes the Puell Multiple, which compares current miner revenue against its 365-day average, has been between 0.56 and 0.98 since late January. That range indicates miners are earning meaningfully below their annual average.
Combined with Bitcoin difficulty hitting a record in February while hashprice simultaneously collapsed to multi-year lows, miners are operating in the tightest margin environment of this cycle.
Bitcoin miners are pivoting to AI hosting. Everyone thinks that's bearish. It's the opposite.

This inactivity is happening as Bitcoin trades near $70,600, having declined roughly 44% from its October 2025 all-time high. The AI migration story compounds the pressure. In recent times, major miners including Core Scientific and Hut 8 have redirected significant power capacity to AI compute hosting under long-term contracts.
These moves have contributed to removing hashrate from the network for years at a time. The miners most likely to be inactive in MPI terms are the ones still operating purely on Bitcoin economics, and those economics are demanding restraint.
The chart from CryptoQuant highlights the previous two instances where the 30-day MPI approached -1. Both preceded meaningful price recoveries, but critically, the recoveries did not begin at the exact moment of peak MPI suppression.
Extreme Miner Inactivity: A Hidden Strength or Silent Warning?
“Historically, the signal becomes more actionable when MPI begins to rise from these lows, indicating re-engagement alongside improving market conditions.” – By @MorenoDV_ pic.twitter.com/Few2hTlmgz

Historical patterns show that Bitcoin’s cyclical lows rarely occur at the exact point where MPI reaches extreme lows. Instead, they tend to form as MPI begins to recover, indicating renewed activity and a shift in market dynamics.
That distinction is the most important nuance in the current reading. The signal is not that the bottom is in. The signal is that one of the largest structural sellers in the market has stepped back. What happens next depends on whether demand-side forces move to fill the vacuum.
The signal becomes more actionable when MPI begins recovering from these lows alongside improving market conditions. Until that recovery takes shape, extreme miner inactivity sits in an ambiguous space. Even though it reduces one headwind, it does not confirm the demand-side engagement needed to drive a sustained directional move.
Watch for a sustained MPI increase above -2.0 as the early warning that miner selling pressure is resuming, a move that would reverse the current bullish supply signal. On the upside, a dovish shift in Fed language, continued ETF inflows or CLARITY Act progression could provide the macro tailwind needed to convert miner inactivity into a confirmed trend reversal.
