Bitcoin security reaches a historic high, but miner revenue drops to a historic low. Where will mining companies find new sources of income?

The current paradox of the Bitcoin network is particularly striking: at the protocol level, it has never been so secure due to high hash rate, yet the underlying mining industry is facing pressure from capital liquidation and consolidation.

The Bitcoin network is currently in a contradictory phase of "high security, low profitability": hash rate continues to remain at a historical high above 1 zettahash, while miners' unit revenue has plummeted to rock bottom, triggering a structural reshuffle in the industry.

On November 27, Bitcoin mining difficulty dropped another 2% at block height 925344, reaching 149.30 trillion, marking the second adjustment downwards this month, yet the block interval still hovers near the 10-minute target. The key indicator for measuring miner revenue, "hash price," has plunged 50% in recent weeks, hitting a historic low of $34.20 per PB per second.

The contrast between high hash rate and low returns stems from the polarization among miners. Small miners unable to secure cheap electricity are exiting at an accelerated pace, while large operators with long-term power purchase agreements and off-grid power plant deployments are steadily expanding.

Even stablecoin giant Tether has suspended its mining project in Uruguay due to uncertainties in energy costs and tariffs, reflecting the survival pressure on small and medium-sized miners. On the surface, hash rate hasn't decreased, but in reality, this is the result of industry consolidation, with the number of entities supporting network security dropping significantly.

The trend toward centralization hides risks: single factors such as extreme weather or grid power restrictions could trigger chain reactions. The capital market has already responded, with the market value of listed mining companies evaporating by nearly $30 billion in November, dropping from a peak of $87 billion to $55 billion before rebounding slightly to $65 billion.

Investors' perception of mining companies is also changing; they no longer see them as "Bitcoin substitutes," but rather as data center businesses with added crypto attributes.

Western miners need to open up new revenue streams by signing long-term power contracts, relocating to flexible grid regions, or taking on artificial intelligence and high-performance computing (HPC) orders.

To judge the industry's direction, three major indicators must be closely monitored: a sharp drop in mining difficulty will confirm the exit of high-cost mining rigs, while a rebound means idle capacity is being restarted; if transaction fees rise due to mempool congestion, short-term profitability may improve; on the policy front, export controls and grid rule adjustments could instantly change the cost structure.
