BlackRock’s 3-Day Bitcoin and Ether Buying Spree Sparks Rally, Then Cooldown

BlackRock’s steady accumulation of Bitcoin and Ether over three consecutive days coincided with a clear price push across both markets. However, after reaching short term highs, BTC and ETH both pulled back as the rally cooled and traders locked in gains. BlackRock Adds BTC and ETH for Three Straight Days BlackRock has accumulated Bitcoin and Ether for three consecutive days, according to onchain tracker Lookonchain. The account said the firm added a combined 9,619 BTC worth about $878 million and 46,851 ETH worth about $149 million over that period. BlackRock ETF Onchain Accumulation. Source: Arkham Intelligence Onchain labels and transfer logs also show fresh movements from Coinbase Prime linked wallets into BlackRock ETF related addresses. The records include multiple Bitcoin transfers into BlackRock’s IBIT Bitcoin ETF tagged destination, alongside several Ether transfers into BlackRock’s ETHA Ethereum ETF tagged destination. The transfers appeared in batches within hours of each other, with repeated deposits of roughly 300 BTC at a time and several ETH moves that include 10,000 ETH sized transfers. While onchain data does not prove who initiated each transaction, the labels point to Coinbase Prime as the source and BlackRock ETF custody addresses as the destination in the latest series of movements. BTC and ETH Prices Move Higher, Then Pull Back During BlackRock Buying Bitcoin and Ether both posted gains during the three day period when onchain data showed BlackRock accumulating BTC and ETH through ETF linked wallets. At the start of the window, Bitcoin traded near the high $87,000 to $88,000 range, before pushing steadily higher over the following sessions. Price climbed above $90,000 and later tested the $93,000 to $94,000 area, marking the strongest levels of the week. As the buying period progressed, Bitcoin momentum slowed. After setting a short term high near $94,000, price began to roll over and moved lower into Jan. 7. By the end of the period, Bitcoin traded near $90,300, giving back part of the earlier advance but still holding above the levels seen before the accumulation phase began. The structure shows a higher high followed by a controlled pullback rather than a sharp reversal. Bitcoin Price Action, Three Day View.

Price broke above $3,100, then extended toward the $3,250 to $3,300 area, where it briefly stalled. This marked the strongest ETH levels during the three day stretch tied to BlackRock inflows.

ETH slipped from the local highs and settled near $3,120, trimming gains but remaining above its early period base. The price action reflects a rise during sustained ETF related inflows, followed by profit taking as the broader market cooled, while both assets kept higher levels compared with where the move began. coinpedia

Canaan’s 3 MW Heat-Recycling Pilot Aims to Turn Crypto Waste Into Greenhouse Energy in Canada

Canaan Inc. launched a 3-megawatt compute heat recovery pilot this week designed to capture waste heat from its liquid-cooled computing equipment and use it to heat a commercial greenhouse, the company said Jan. 6. The initiative marks a fresh step in efforts by a major crypto hardware maker to improve energy efficiency and cut the environmental footprint of high-density computing. The pilot is taking place at a greenhouse facility in Manitoba, Canada , operated by Bitforest Investment Ltd., and will run for an initial 24-month term, executives said. Under the agreement, Canaan will install 360 Avalon A1566HA-460T liquid-cooled computing servers and four liquid-cooling container modules that together generate about 3 MW of usable heat. The system is built to integrate with the greenhouse’s existing electric boiler heating loop. Canaan said heat captured from computing servers will preheat intake water for electric boilers through a closed-loop heat exchange system. Based on current estimates, about 90 % of the electricity consumed by the servers could be captured and transferred as useful heat rather than lost to the atmosphere. Used heat will help sustain internal climate conditions for greenhouse crops, such as tomato plants, during cold months. Pilot Tests a New Energy-Reuse Model The project aims to validate whether compute waste heat can serve as a reliable supplemental heat source in agricultural settings, particularly in colder climates where heat demands are high. Canaan executives said the pilot will measure key performance indicators such as heat-recovery efficiency, system stability and maintenance intensity once fully operational. The pilot also tests a low all-in power cost of approximately US $0.035 per kilowatt-hour, which includes power consumption, routine operations, troubleshooting and maintenance. If Bitforest participates in grid demand-response programs or sells surplus power back to the grid, Canaan would share in the resulting economic benefits. Canaan said its liquid-cooling technology produces hot water above 75 °C, making recycled heat directly usable for greenhouse operations without additional heating stages. The company also noted that efficient heat reuse could remove the need for industrial cooling towers typically required for data centers with liquid-cooled equipment. Broader Sustainability Push Canaan described the Manitoba pilot as part of its broader energy efficiency and sustainability initiatives. The company has explored other heat reuse projects, including industrial applications and consumer-oriented products that make use of energy otherwise wasted in computing operations. Large greenhouse operations have traditionally relied on fossil-fueled boilers for primary heat. In regions such as Canada, policies that put a price on carbon emissions have encouraged greenhouse operators to seek lower-carbon heating options. Canaan’s approach seeks to leverage high-density computing as a dual-purpose asset — delivering computing performance while generating heat that supports agricultural production. The pilot’s success could influence how other data-intensive companies think about integrating waste-heat recovery into commercial and industrial settings. coinpedia
