The Bitcoin mining industry is showing new characteristics: expanding scale, improving efficiency, and accelerating greening.

A recent industry report covering about 48% of the Bitcoin network's hash rate shows that Bitcoin mining is transforming into a capital-intensive, energy-centric data center business. The industry exhibits three new characteristics: rapid improvement in the efficiency of dedicated chips, significant inflow of institutional capital, and an increasingly green energy structure.

Industry Scale and Growth

In 2024, the cumulative electricity consumption of the Bitcoin mining industry reached 138 terawatt-hours, but the energy consumption per unit of work decreased by 24% to 28.2 joules per terahash. The global hash rate rose to 796 EH/s, demonstrating miners' ongoing investment motivation. The latest 5nm and 3nm chip designs have energy consumption below 20 J/TH, and it is expected that chips with efficiency improvements of up to double, below 10 J/TH, will be launched in 2025-2026.

Acceleration of the Greening Process

Sustainable energy (renewable energy and nuclear energy) has met 52.4% of the Mining load, an increase of 15 percentage points from the previous year. The industry's annual greenhouse gas emissions amount to 39.8 million tons of CO2 equivalent, accounting for only about 0.08% of global emissions. Carbon intensity has dropped to 288 grams of CO2 equivalent per kilowatt-hour, a decrease of 34% compared to 2021. 70.8% of companies have adopted mitigation measures, including the use of renewable energy certificates, carbon offsets, and waste heat reuse.

Changes in Regional Distribution

The United States accounts for about 75% of the survey report's hashing power. Paraguay, the UAE, Norway, and Bhutan have emerged as new secondary hubs. Approximately 41% of the global hashing power is controlled by publicly listed miners, making a mixed debt and equity capital structure possible.

Cost and Profit Analysis

The median delivery electricity cost is $45 per megawatt hour. Including all operating expenses, the average total cost is $55.5 per megawatt hour. The surge in Bitcoin prices in the fourth quarter of 2024 has driven the industry's "hashrate profit" to an all-time high. The cost of mining one Bitcoin ranges between $14,000 and $36,000, with the lowest cost operators still profiting during market downturns.

Risks and Challenges

The main risks facing the industry include rising energy prices, policy uncertainty, and concentration of chip supply. Common coping measures include long-term electricity hedging, geographic diversification, and vertical energy ownership. Proposals for federal energy consumption taxes in the United States, carbon taxes in Europe, disruptions in chip supply, and long-term low prices of Bitcoin are all potential threats.

Future Development Trends

The industry is developing towards the integration of AI/HPC, vertical energy integration, and green Bitcoin premiums. It is expected that by 2025, the enterprise value/EBITDA multiple of major miners in North America will be 4.8-6.2 times. Key catalysts for the next 12 months include net inflows into ETFs, the shipment of the next generation of efficient chips, grid service revenue policies, and the finalization of the EU's sustainability rules for the crypto asset market.

Investors should pay attention to miners that are vertically integrated, low-cost, highly efficient, and use a high proportion of renewable energy, while being cautious of operators that have high leverage, high electricity costs, and use outdated equipment.
