Bitcoin miners are navigating the most severe profitability squeeze in the network’s history, and a new analysis from crypto market maker Wintermute argues that passive hope for the next bull market is a failing strategy. According to the firm’s report, miners must fundamentally reinvent their business models—shifting from pure coin production to hybrid roles as infrastructure and treasury managers—to survive until the next halving cycle.
Jasper De Maere, an analyst at Wintermute, frames the current mining epoch as structurally distinct from the bear markets of 2018 and 2022. While Bitcoin’s protocol still enforces a 50% reduction in block rewards every four years, the price appreciation this time has not kept pace. “On a rolling four‑year basis, Bitcoin has only returned about 1.15x in this epoch, far below the 10x–20x multiples seen in earlier cycles,” De Maere notes. This disconnect means miner revenue is shrinking in real terms, a reality that past hypergrowth masked.
Historically, explosive price rallies post-halving bailed out miners with weak margins. Today, with institutional capital flowing through ETFs and corporate treasuries adopting Bitcoin as a macro asset, those 20x price surges are increasingly improbable. For miners whose business plans assumed permanent hypergrowth, Wintermute characterizes this shift not as a temporary downturn but as a permanent regime change.
Margins Are Getting Crushed
Bitcoin mining’s cost structure is brutally simple: energy and compute. That simplicity leaves little room for maneuver when revenue falls. Wintermute’s data reveals that gross margins in the current epoch peaked around 30%—a level that marked the absolute bottom in prior bear markets, not a high point. In contrast, earlier cycles featured extended periods where miners enjoyed 70–80% margins. What was once a “bad” quarter now looks like a “good” one.
Transaction fees, often touted as a secondary revenue stream, have failed to offset the squeeze. While fee spikes during periods of hype or mempool congestion are visually dramatic on charts, they are fleeting. Over time, fees rarely contribute more than a few percent of total miner revenue. Wintermute’s cycle‑by‑cycle margin analysis shows that even when fees are included, the lines barely diverge. “The protocol’s built‑in second revenue stream is not acting as a reliable backstop,” the report states.
The Fee Market’s Structural Limitations
The fee market’s inability to scale with network activity is a core part of the problem. Unlike earlier cycles where retail frenzy drove sustained fee pressure, today’s transaction volume is increasingly dominated by institutional activity and layer‑2 solutions that settle off‑chain. This suppresses on‑chain fee potential, leaving miners dependent on the block reward—which is now half of what it was—without a meaningful compensatory increase in fee income.
The AI Pivot Is an Opportunity for a Few
Faced with collapsing margins, many miners are looking toward high‑performance computing (HPC) and artificial intelligence workloads. The logic is compelling: AI firms and big tech are scrambling for secure, low‑latency power and data center capacity, and they lack the patience for new grid connections and construction. Miners already control sites with cheap power and existing build‑outs, making them natural partners.
Wintermute highlights a dramatic revaluation in this shift. Sites previously valued at $1–$7 per watt for pure mining have fetched close to $18 per watt when repositioned for AI compute. This premium is driven by deals like HUT8’s collaboration with Google and Anthropic, which demonstrate a path to higher-margin, longer‑term contracts. Public‑market investors have rewarded such pivots with richer valuations and cheaper capital via equity or convertible debt.
However, the opportunity is highly selective. Not every mining operation possesses the geographic location (proximity to power grids and low‑latency networks), balance sheet strength, or operational expertise to transition into a data‑center business. The AI pivot will likely consolidate the industry’s upper tier, transforming a select few into infrastructure companies while leaving others behind.
Putting “Idle” Bitcoin to Work
For miners unable or unwilling to pivot to AI, Wintermute identifies a second, underutilized lever: active treasury management. Collectively, miners hold nearly 1% of all Bitcoin—a legacy of the “HODL” strategy from earlier cycles. Meanwhile, many listed miners have been selling portions of their treasuries to cover operating costs and debt, with some nearly liquidating their holdings.
Wintermute argues that instead of letting these reserves sit idle—or being forced to sell during liquidity crunches—miners should treat their BTC as a working asset. On the active side, this involves derivatives strategies like covered calls and cash‑secured puts to generate yield, albeit with accepted market risk. On the passive side, miners can deploy coins into on‑chain lending markets, such as the wrapped‑BTC (wBTC) market on lending protocol Wildcat, to earn interest income.
These strategies require sophisticated risk management and regulatory navigation,
