Bitcoin Miner Activity Hits Historic Low
Bitcoin miners are under pressure again, but the latest onchain signal is not entirely bearish. According to ForkLog, citing CryptoQuant analyst Ignacio Moreno de Vicente, the Miner Position Index (MPI) recently fell to -1.04, the third-lowest level in history. ForkLog framed the move as a potentially bullish signal because it suggests miners are selling far less BTC than usual, reducing one source of market supply.
That headline matters because miners sit in a unique place in the Bitcoin market. They are not just investors or speculators. They are one of the ecosystem’s natural, recurring sources of new coin supply. When miners sell aggressively, they can add meaningful pressure to the market. When they hold back, that pressure eases. So a historically low miner activity reading is not just an obscure metric for data nerds. It is a clue about how one of Bitcoin’s most structurally important groups is behaving right now.
What the Miner Position Index actually measures
The Miner Position Index, or MPI, is an onchain metric used to estimate whether miners are moving more or less BTC than usual, especially toward selling activity. ForkLog’s English summary says the metric tracks whether miners are selling more or less of their holdings than normal, and CryptoQuant’s miner flow charts describe miner-linked wallet transfers as a way to evaluate supply conditions in the market. When MPI is deeply negative, it generally suggests miners are not rushing to sell.
That is why Ignacio Moreno de Vicente called the latest reading bullish. A low MPI does not guarantee a rally, but it can indicate that miner-driven sell pressure is fading. In Bitcoin, where new issuance is already limited by the protocol, any slowdown in forced or routine miner selling can matter, especially during periods when broader market demand is trying to stabilize.
Why miners may be selling less now
At first glance, low miner activity might look like a sign of strength. But the deeper picture is more complicated. In 2026, Bitcoin miners are operating in one of the toughest environments since the April 2024 halving. CoinShares said in its Q1 2026 Bitcoin mining report that Q4 2025 was the most challenging quarter for miners since the halving, with a sharp BTC price drawdown and near-record hashrate compressing hash prices to multi-year lows. It also estimated that the weighted average cash cost to produce one bitcoin among publicly listed miners rose to roughly $79,995 in Q4 2025.
That changes how the low MPI reading should be interpreted. It may be bullish from a pure supply perspective, but it is also consistent with an industry under stress. When margins get squeezed, miners do not always respond by dumping more coins immediately. Some reduce activity, delay hardware upgrades, shut off older machines, restructure operations, or simply wait for better conditions. CoinShares said current economics do not incentivize a broad hardware refresh cycle and warned of further capitulation among higher-cost operators unless Bitcoin price recovers materially.
Mining economics in 2026 are still brutal
The pressure on miners is not theoretical. CoinShares said current hash prices have made it unfeasible to run many older mining models, estimating that 15% to 20% of the global mining fleet may be unprofitable at current economics if electricity costs are high enough. Hashrate Index’s recent weekly roundup also showed how sensitive the sector remains to small changes in hashprice, difficulty, and BTC price, even when short-term network conditions improve.
There were also signs of outright stress earlier this year. ForkLog reported in February that Bitcoin’s network hashrate fell to around 870 EH/s, the lowest level since June 2025, as winter storms in the U.S. disrupted operations and hashprice dropped to $34.8 per PH/s per day. That episode was a reminder that miner weakness is not only about price. Weather, power reliability, and operational costs can also hit the industry hard.
In other words, the MPI collapse is happening against a backdrop where many miners are already stretched. That makes the signal more interesting. If miners are stressed but still not flooding the market with BTC, then either they are waiting for better prices, or many weaker operators have already reduced activity enough that the usual selling flow has thinned out. Both interpretations can support a more constructive supply picture for Bitcoin.
Why a low MPI can be bullish for Bitcoin price
Bitcoin’s market is always a balance between supply and demand, and miners are part of the supply side. They do not control the whole market, but they do create a steady flow of coins that often gets sold to cover electricity, infrastructure, and debt costs. If that selling slows, the market has one less headwind to fight through.
That is the main bullish argument behind the current MPI reading. ForkLog’s article directly described the move as a bullish signal, and that logic is straightforward: fewer miner outflows mean less near-term sell pressure from one of the network’s natural sellers. In a market that is already sensitive to shifts in liquidity and sentiment, that can matter more than many traders assume.
There is also a psychological angle. Miner behavior often gets watched closely because miners are viewed as informed participants with intimate exposure to network economics. When they stop selling aggressively, some investors interpret that as a sign they expect better prices ahead or simply do not want to liquidate at unattractive levels. That interpretation is not always correct, but it helps explain why onchain miner metrics can influence broader market sentiment.
But this is not a simple all-clear signal
Still, it would be a mistake to read the MPI drop as pure good news. Sometimes low miner activity reflects confidence. Other times it reflects stress, reduced production, or an industry too squeezed to behave normally.
CoinShares’ latest report suggests caution here. It says many miners are now being forced to adapt by cutting costs, turning off less efficient rigs, or pivoting parts of their infrastructure toward AI and high-performance computing. The report even says listed miners could derive as much as 70% of their revenue from AI by the end of 2026, a sign that some operators are no longer relying on Bitcoin mining as their main growth engine. That is not the backdrop of a comfortable, thriving mining sector. It is the backdrop of a sector trying to survive.
That matters because a stressed mining sector can still become a source of future volatility. If BTC price weakens further, some miners may eventually be forced to liquidate more aggressively. CoinShares said if prices remain below $80,000 for the rest of the year, hashprice could keep falling unless enough hashrate drops off to stabilize conditions. So while the current MPI reading reduces immediate selling pressure, it does not eliminate the structural fragility underneath the industry.
What investors should watch next
The next step is not to watch MPI alone. Investors should monitor it alongside hashprice, network difficulty, hashrate, and Bitcoin price itself. If miner activity remains muted while BTC stabilizes or strengthens, the supply-side picture could improve meaningfully. If, on the other hand, BTC weakens and mining margins remain under pressure, today’s quiet miner behavior could give way to another wave of capitulation later.
There are already signs the market is watching these variables closely. Recent media coverage highlighted that Bitcoin miners were effectively losing money on production under some assumptions, while Hashrate Index continues to track weekly changes in network conditions and machine economics. This tells you the mining side of the market remains a live macro variable for Bitcoin in 2026, not just background noise.
Conclusion
Bitcoin’s miner activity index has fallen to one of the lowest readings ever recorded, and that is meaningful. According to ForkLog and CryptoQuant commentary, the MPI at -1.04 suggests miners are selling far less than usual, which reduces one source of BTC supply and can be read as a bullish signal.
But the wider story is more nuanced. Miners are not quiet because the business is easy. They are quiet in a period of compressed margins, weak hashprice economics, and rising strategic pressure across the industry. That makes the signal interesting precisely because it sits at the intersection of two opposing forces: miner stress on one side, lower immediate sell pressure on the other. For Bitcoin investors, that is the real takeaway. The MPI collapse does not mean mining is healthy. It means the market may be getting temporary relief from one of its most consistent sellers — and in a tight market, that can still matter a lot.
