BitMine Immersion Technologies, a crypto firm backed by Fundstrat's Tom Lee, has expanded its Ethereum position again despite mounting unrealized losses. The company said Monday it bought 101,901 ETH last week, lifting total holdings to about 5.08 million ETH. BitMine added that its combined cryptocurrency assets and cash reserves stand at roughly $13.3 billion. (Source: Wu Shuo Blockchain) The purchase comes one week after another major buy of 101,627 ETH, which was its largest increase since December. Even with these large-scale additions, BitMine is sitting on more than $6.5 billion in unrealized losses, based on total investment of around $17.6 billion, underscoring how recent Ethereum price swings have hit crypto-treasury strategies. Shares of BMNR, listed on the New York Stock Exchange, are down more than 20% year to date, according to Yahoo Finance. BitMine continues to earn yield on part of its holdings. The company has staked about 3.7 million ETH, collecting rewards for helping secure the Ethereum network and validate transactions, creating an income stream that can persist through price drawdowns. (Source: Dropstab) Market stabilization signs emerge BitMine's buying spree coincides with early signs of stabilization across crypto after a slide that extended through March. TradingView data show Ethereum climbed back above $2,400 last week after dipping to roughly $1,800 earlier this year. Even after the rebound, ETH remains down about 23% for the year. The move has tracked improving sentiment across equities and other risk assets, but volatility continues to test companies running large digital-asset treasuries. With reserves highly exposed to price changes, firms can still rack up sizable unrealized losses during downturns even while adding to positions. Staking income may help, but it often cannot fully offset sharp declines in asset values, leaving balance sheets sensitive to market cycles.

CoinMarketCap reported that Strategy, the world's largest publicly traded Bitcoin holder, kept adding to its position last week as BTC traded above $77,000. In an 8-K filed with the U.S. Securities and Exchange Commission on Monday, the company disclosed it bought 3,273 bitcoins for $255 million between April 20 and 26, paying an average $77,906 per coin. The purchases lifted Strategy's overall cost basis to $75,537. Strategy now holds 818,334 BTC, acquired for about $61.8 billion. CoinGecko data puts the market value of that stash at roughly $63.6 billion at the time of writing. Unlike the prior week's 34,164-BTC buy—its third-largest single purchase on record—the latest accumulation did not involve STRC, the company's perpetual preferred securities. SEC filings show the transaction was funded entirely through Strategy's Class A common stock (MSTR): the company sold 1.45 million shares to raise $255 million. The STRC Live tracking tool had also flagged no STRC-related activity during the week. Co-founder Michael Saylor had signaled on Sunday that the company would keep buying and shared a chart summarizing Strategy's 107 Bitcoin purchases since 2020. With 818,334 BTC, Strategy's holdings now exceed BlackRock's approximately 812,300 BTC held on behalf of clients. Wallet Pilot data shows Strategy remains behind the combined holdings of cryptocurrency fund issuers, totaling around 1.32 million BTC. Bitcoin advocate and Strategy investor Adam Livingston said he expects Strategy to hold 1.2 million BTC by the end of 2026, implying additional purchases of 381,666 BTC. So far this year, Strategy has bought 144,551 BTC, or about 36,137 BTC per month.

Aave said DeFi United has published a remediation plan to restore backing for KelpDAO's rsETH following an April 18 bridge incident.

It also plans to temporarily adjust the rsETH oracle price via governance to unwind exploiter-related positions on Aave and Compound. WETH and rsETH markets across multiple chains will remain frozen until operations return to normal. Source:
