A $300 home miner just hit a $250,000 Bitcoin block reward — but the odds are still brutal

A solo miner using a machine with roughly 6.5 TH/s of hash rate mined Bitcoin block 973,413 on Oct. 27, earning a 3.14 BTC reward worth just over $250,000 at the time, according to public data from CKPool cited by PANews. Altair Tech said the device was likely a Canaan Avalon Nano 3S, a compact home miner that sells for a few hundred dollars and draws 140 watts of power. The report places the win in a broader pattern. PANews said similar low-power devices also landed major solo mining rewards earlier this year, including another Nano 3S on May 30 and a Bitaxe Gamma on July 10. Even so, the article stresses that these cases remain statistical outliers. Using the network difficulty of 140.58T and estimated global hash rate levels around 1,000 EH/s, the report calculates that a single Nano 3S would have an annual chance of roughly 1 in 2,900 to 1 in 3,200 of mining a block. The piece also links growing interest in home miners to pressure on industrial mining economics. It cites falling hashprice, weaker fee income, and rising difficulty, while several listed miners have shifted power capacity toward AI-related business lines. In that setting, small home miners are being marketed less as profit machines and more as low-noise devices that combine hobbyist participation, occasional pool income, and household heating.

Why MARA Stock Rose After a $1.71 Billion Loss and What Its AI Data Center Pivot Means

MARA Holdings reported a steep net loss of $1.71 billion for the fourth quarter of 2025, yet its shares still climbed 13% in premarket trading as investors focused on the company’s shift beyond pure Bitcoin mining. The main reason for the quarterly loss was a $1.5 billion negative fair-value revaluation of digital assets after Bitcoin prices declined, highlighting how accounting treatment can heavily distort miners’ reported earnings. Revenue for the quarter fell 6% to $202.3 million, while full-year revenue rose to $907.1 million even as annual net income swung from a $541 million profit in 2024 to a $1.31 billion loss in 2025. Operationally, MARA mined 2,011 BTC in Q4 and 8,799 BTC for the full year, both below prior comparison periods, while ending the year with 53,822 BTC on its balance sheet, including 15,315 BTC pledged as collateral. At a quarter-end Bitcoin price of $87,498, those holdings were worth nearly $4.7 billion. At the same time, MARA unveiled a strategic pivot toward AI and high-performance computing infrastructure through a joint venture with Starwood Digital Ventures and its acquisition of a 64% stake in Exaion. The move reflects a broader industry trend as mining firms such as Cipher and Bitfarms repurpose power-intensive infrastructure to diversify revenue amid post-halving pressure and shrinking mining margins.

Bitcoin miner MARA Holdings reported a $1.71 billion net loss for Q4 2025, driven by a $1.5 billion negative revaluation of digital assets due to declining Bitcoin prices. Despite the loss, premarket stock rose 13% as investors focused on the company's strategic pivot toward AI and high-performance computing (HPC) data centers. Revenue fell 6% to $202.3 million. For the full year, MARA posted a $1.31 billion net loss compared to a $541 million profit in 2024. The company mined 2,011 BTC in Q4, down 6% quarter-over-quarter, and held 53,822 BTC valued at ~$4.7 billion. MARA announced a joint venture with Starwood Digital Ventures to develop over 1 GW of AI/HPC infrastructure, with potential expansion to 2.5 GW, and acquired a 64% stake in Exaion. The move mirrors a broader industry trend as miners repurpose energy-heavy facilities for AI and HPC to diversify revenue amid post-halving margin pressure.
