The Nvidia-backed startup Starcloud plans to begin Bitcoin mining in space later this year, once its second spacecraft is launched into orbit.

CleanSpark (CLSK), a U.S.-based bitcoin mining company that operates large-scale data centers, sold nearly all of the bitcoin it mined last month in order to secure funding for artificial intelligence (AI) and high-performance computing (HPC) initiatives.

Independent analyst Shanaka Perera explained how much Iran is earning from Bitcoin mining, despite the cryptocurrency having declined 46% since October 6, 2025.

The mining company owned by the sons of U.S. President Donald Trump — American Bitcoin — reported a $59 million loss for the fourth quarter of last year. In 2025, unrealized losses on its bitcoin reserves reached $227 million amid a decline in cryptocurrency prices

The recent sharp downturn in the cryptocurrency market has put renewed pressure on the Bitcoin mining sector. According to a new analytical note published by Rosenblatt, the drop in Bitcoin’s price has made mining unprofitable for many companies.

Mining

A miner rented 450 PH/s of computing power for 90 minutes and managed to find a block containing 3,278 transactions. According to estimates by AtlasPool, the probability of such an outcome was only 0.4485%.

The company said it sold cryptocurrency on the open market for USDT stablecoins at an average price of about $68,000 per BTC, which generated proceeds of approximately $305 million.

A researcher stated that only 10,200 BTC on legacy addresses are under real threat from quantum computers. Bendiksen disagreed with the results of a study conducted in May 2025 by Chaincode Labs analysts Anthony Milton and Clara Shikhelman. According to their estimates, 20% to 50% of bitcoins in circulation are vulnerable to quantum computing.

Shares of CleanSpark (CLSK) fell 19.13% during the main trading session and dropped an additional 8.6% after the close, reaching $7.55. On Friday, February 6, the price saw a slight premarket recovery to $8.06.

According to GoMining, at the end of 2025 the average daily hashrate of the Bitcoin network remained above the 1 ZH/s level for seven consecutive days. The increase in computing power was the result of large-scale hardware upgrades and the expansion of data centers.

Stablecoin issuer Tether has released an open-source operating system for Bitcoin mining. Tether’s Mining OS is an operational platform that can be scaled to industrial levels across different geographic regions. It is a highly modular peer-to-peer encrypted networking layer that supports numerous miners, containers, sensors, monitoring devices, pools, and more, wrote Tether CEO Paolo Ardoino.

The drop in hashrate was caused by a winter storm across the United States. The natural phenomenon was marked by freezing rain that led to power line outages, snow, and strong wind gusts. Currently, more than one million households in the U.S. are without electricity. The weather affected power generation, which resulted in miners being shut down, TheMinerMag reports.

Cryptocurrency mining equipment manufacturer Canaan has received a delisting warning from Nasdaq. This is the second crypto company to receive such a notice from the stock exchange over the past two months.

At the end of December, the total capacity of Bitdeer’s mining farms reached 71 exahashes per second (EH/s), accounting for about 6% of the global Bitcoin hashrate. The report includes both the mining power of the company’s own facilities (55.2 EH/s) and the hashrate of third-party mining equipment hosted at Bitdeer’s sites.

Analysts said that oil extraction in Venezuela could open a new phase of mining expansion — especially in regions able to secure long-term contracts for electricity supply. In their view, only a portion of Venezuela’s oil reserves would be enough to have a noticeable impact on energy prices. This could provide meaningful support for miners, whose profitability is declining partly due to rising electricity costs. Following the seizure and capture of Venezuelan President Nicolás Maduro, oil prices fell, which should also benefit miners, as their electricity expenses are linked to oil prices.
