Bitdeer has zeroed out its Bitcoin reserves, and that says a lot about what’s really happening in the mining sector right now.

The company that once accumulated over 2,400 BTC last November started selling continuously until everything was gone around February. Now it follows a simple rule: mine and sell on the same day. It looks like desperate action, but the company’s numbers tell a different story—$2.248 billion in revenue in Q4 2025, $705 million in profit, and mining capacity of 71.0 EH/s. Everything is growing exponentially. So why would a company with a positive balance sheet and a record of hash power choose to offload everything now?

The answer lies in something the market pretended not to see: miners were never really coin accumulators out of faith. That talk of HODLing as a corporate strategy? Something that only the minority believes. When Bitcoin was launched years ago, the logic was simple—extract, sell, convert into cash. BTC was a product, not an asset. MicroStrategy changed that narrative a few years back, and the whole industry followed the wave, but few people actually stuck with it.

The data makes this clear. From January to November 2025, the top 10 publicly traded miners mined about 40,700 BTC and sold 40,300. The sale rate is close to 99%. These companies never truly accumulated. Miners are energy arbitrageurs—they turn cheap electricity into revenue. While the price of BTC was rising, whether to sell or not was a matter of stance. But once BTC drops below the cost of mining, selling stops being a stance and becomes an instinct for survival.

The sector is being squeezed from three directions at the same time. First, the 2024 halving cut block rewards in half while energy, machines, and operating costs don’t move. Many miners are operating at a loss. Second, the balance sheet numbers turned ugly—revenue is rising but losses are too. Marathon had $9.07 billion in revenue but a $13.1 billion loss. Hut 8 went from profit of $3.31 billion to a $2.48 billion loss. Third, the macroeconomic environment has worsened. Trump raising tariffs, Bitcoin falling below $65,000, and is now trading at $77.82 thousand. Widespread risk.

So what’s the way out? Transformation. Miners are using their cheap energy infrastructure and data centers to move into AI and high-performance computing. Bitdeer is pushing its AI cloud services; Cipher changed its brand from Mining to Digital. The logic checks out—they have cheap power contracts and scalable space, exactly what’s missing for AI infrastructure.

But real progress is far more conservative than the narrative suggests. TeraWulf generated only $970 million in HPC revenue in Q4, less than 30% of the total. Winning customers, executing contracts, and scaling capacity takes time. Meanwhile, debt is due now.

What’s interesting is that while BTC fell 17% in a month, mining stocks rose. TeraWulf jumped 31%, Cipher rose 8%, and Hut 8 rose 6%. This shows that capital markets have reappraised these companies—not as levers for the price of Bitcoin, but as potential AI infrastructure. The criterion has shifted from who holds how many BTC to who has locked in cheap energy for longer, who has data center assets with transformation potential, and who has the balance sheet to survive the transition.

At bottom, miners were never the most devoted believers. They’re the most rational participants. When mining is profitable, they mine. When accumulation sustains valuation, they accumulate. When selling provides resources for transformation, they sell without hesitation. That’s the basic principle of business.

The real question is: once the AI/HPC transformation story is fully priced in by the markets, what will these companies present to support the next round of valuation? If at that time Bitcoin has risen but the transformation businesses still aren’t mature, will these miners go back to telling the story of accumulating coins? Cycles repeat, narratives are refreshed. But in every winter, survival always matters more than faith.
