Khai thác Bitcoin là quá trình phi tập trung đảm bảo mạng lưới Bitcoin, xác thực giao dịch và tạo ra bitcoin mới. Dưới đây là phân tích cách nó hoạt động: Những điều cơ bản
Mục đích: Bitcoin hoạt động trên một chuỗi khối, một sổ cái công khai của tất cả các giao dịch. Khai thác đảm bảo rằng sổ cái này là chính xác, không thể bị giả mạo và được cập nhật theo cách không cần tin cậy (không cần một cơ quan trung ương như ngân hàng).
Cách nó diễn ra: Các thợ mỏ sử dụng máy tính mạnh mẽ để giải quyết các câu đố toán học phức tạp. Những câu đố này liên quan đến việc tìm một số cụ thể (gọi là "nonce") mà khi kết hợp với dữ liệu giao dịch và thông tin của khối trước, tạo ra một băm (một chuỗi ký tự duy nhất) đáp ứng các tiêu chí nhất định - thường bắt đầu bằng một số cụ thể các số không. Điều này được gọi là Chứng minh công việc (PoW).

French energy major Engie SA is evaluating whether to integrate Bitcoin mining data centers and large-scale battery storage at its newly operational Assu Sol solar complex in northeastern Brazil.

Key Takeaways
Engie SA is studying Bitcoin mining and battery storage at its Assu Sol solar plant in Brazil.The goal is to monetize curtailed electricity caused by grid constraints.Mining rigs could act as flexible energy buyers behind the meter.A decision and rollout would likely take up to two years.
The move is aimed at capturing value from electricity that would otherwise go unused due to grid bottlenecks.
The Assu Sol project - now Engie’s largest solar asset worldwide - received full commercial approval from Brazilian authorities on February 13, 2026. With a peak capacity of 895 MWp and 753 MW of installed capacity, the BRL 3.3 billion ($640 million) development spans 16 plants and more than 1.5 million photovoltaic panels.
Turning Wasted Power Into Revenue
Brazil’s rapid expansion in renewable generation has created a structural imbalance: wind and solar capacity have grown faster than transmission infrastructure. Since 2023, this has led to recurring curtailment - forced shutdowns when the grid cannot absorb excess electricity.
For operators, that means lost megawatt-hours and lost revenue.
Engie is now studying whether Bitcoin mining facilities could function as a “flexible offtaker,” consuming surplus power directly behind the meter. Unlike traditional industrial demand, mining rigs can be switched on and off almost instantly, allowing them to operate only when excess electricity is available.
The company’s focus is not speculative crypto exposure, but rather revenue protection. By monetizing curtailed output, Engie would aim to improve plant economics without depending on wholesale power prices.
Regulatory Tailwinds
Brazil has introduced supportive trade measures that could reduce setup costs. The country’s foreign trade council has temporarily reduced import duties to zero on high-efficiency mining equipment through January 2028. That incentive lowers capital expenditure barriers for energy-linked mining operations.
At the same time, Engie is also assessing utility-scale battery storage as an alternative. Batteries would store surplus power during oversupply periods and discharge it later when demand and grid prices improve.
Not an Immediate Shift
According to Eduardo Sattamini, Engie’s country manager in Brazil, implementation would not happen overnight. The company estimates roughly two years would be required to develop and deploy any mining or storage solution.
The broader strategy reflects a growing trend among renewable developers worldwide: pairing generation assets with flexible demand or storage to stabilize revenues in increasingly saturated renewable markets.
If executed, the Assu Sol initiative would position Engie among the largest global utilities experimenting with energy-backed Bitcoin mining as a grid-balancing mechanism rather than a speculative venture.

Hut 8 released its fourth-quarter and full-year 2025 results on February 25, revealing a dramatic transformation in its business model.

Key Takeaways
Hut 8 Revenue jumped 179% year over year, but missed expectations.Net loss was driven mainly by a large non-cash Bitcoin revaluation.Gross margin improved significantly to 60%.AI and compute now dominate revenue, marking a clear strategic pivot.Investors focused on the AI growth story, pushing shares higher.
While the company posted a steep net loss tied to Bitcoin’s price volatility, revenue surged triple digits as management accelerated its shift toward AI infrastructure and high-performance computing.
The market appeared to look past the headline loss. Shares climbed roughly 2.4% following the announcement, suggesting investors are increasingly focused on the company’s long-term AI roadmap rather than short-term crypto accounting swings.
Revenue Jumps 179%, But Earnings Swing Deeply Negative
For Q4 2025, Hut 8 reported revenue of $88.5 million, up 179% from $31.7 million in the same quarter a year earlier. However, the figure fell short of analyst expectations near $95.6 million.
The bottom line showed a sharp reversal. The company posted a net loss of $301.8 million, compared to a $152.0 million profit in Q4 2024. Adjusted EBITDA came in at negative $347.8 million, down from positive $310.6 million a year earlier.
Despite the steep loss, earnings per share of -$0.1101 beat analyst forecasts, which had projected a wider loss in the range of roughly -$0.12 to -$0.25 per share.
Gross margin improved significantly to 60%, up from 36% in Q4 2024, indicating stronger underlying operating performance even as accounting losses weighed on net results.
Bitcoin Accounting Weighs on Results
Management attributed the majority of the net loss to a $401.9 million unrealized mark-to-market loss on its Bitcoin holdings. The company ended the year with approximately 13,696 BTC valued at around $1.4 billion, down from $1.6 billion in Q3 following a roughly 25% drop in Bitcoin’s price during the quarter.
Executives described this as “Bitcoin noise,” emphasizing that the loss was non-cash and largely accounting-driven. Excluding the unrealized crypto revaluation, operational metrics showed improvement, particularly in margin expansion and segment performance.
Compute Segment Becomes Core Revenue Engine
The company’s Compute segment has now become its primary growth driver. It generated $81.9 million in Q4, accounting for 92% of total quarterly revenue. The segment includes Bitcoin mining, GPU-as-a-Service, and cloud-based infrastructure offerings.
CEO Asher Genoot characterized 2025 as the year of the “power-first” pivot, marking Hut 8’s transition away from being viewed solely as a Bitcoin miner toward becoming a long-term AI infrastructure provider.
Development Pipeline Expands Toward AI Infrastructure
Hut 8’s development pipeline has expanded to 8,500 megawatts of energy capacity, with 330 MW currently under construction. A key project is the 245 MW River Bend campus, designed as a large-scale AI data center.
The River Bend facility is backed by a 15-year, $7.0 billion lease agreement with Fluidstack, supported by Google. Delivery of the project is expected to begin in Q2 2027, positioning Hut 8 as a major player in AI-focused data infrastructure.
Strategic Reset Beyond Bitcoin
The latest results underscore a broader strategic reset. Rather than relying purely on Bitcoin mining revenue, Hut 8 is attempting to build more predictable, long-duration cash flows from AI data centers and high-performance computing contracts.
While crypto volatility continues to introduce earnings swings through mark-to-market adjustments, investors appear increasingly willing to separate operational progress from Bitcoin price fluctuations. The modest post-earnings stock rally reflects growing confidence that the company’s AI infrastructure pivot may define its next growth cycle more than its digital asset treasury.

Một sự phát triển đáng kể đã xảy ra trên mạng Bitcoin ( $BTC ). Một thợ mỏ solo, người đã thuê sức mạnh băm chỉ với $75, đã vượt qua mọi khó khăn và nhận được phần thưởng khối, tạo ra hơn 3.1 BTC doanh thu. Thành tựu này tương đương với khoảng $200,000 thu nhập.

Thợ mỏ đã thuê tối thiểu 1 Petahash/s (PH/s) sức mạnh thông qua thị trường sức mạnh băm được cung cấp bởi Braiins.

Với tỷ lệ băm mạng Bitcoin hiện tại, xác suất tìm thấy một khối với công suất 1 PH/s được ước tính khoảng một trong 1.1 triệu khối. Điều này thể hiện xác suất cực kỳ thấp, tương đương với khoảng 21 năm khai thác. Các chuyên gia so sánh tình huống này với “chơi xổ số.”
