Ethereum short-term profit-taking accelerates. The mysterious Ethereum whale group “7 Siblings” sold $88.2 million worth of ETH over the past 15 hours. According to blockchain analytics platform Lookonchain, the group offloaded 19,461 ETH at an average price of $4,532. This brings 7 Siblings’ total Ether holdings to 1.21 million ETH, valued at $5.6 billion.
Between February 3 and April 7, the group acquired 103,543 ETH. The total cost of these purchases reached $229.7 million, with an average price of $2,219. Notably, in early April, they bought 24,817 ETH for $42.2 million. Transactions were carried out across multiple wallets, showing a deliberate strategy to manage large holdings.
Whale Sales and Short-Term Profit-Taking
The largest ETH movements involved deposits to Aave v3. This strategy allowed the whale group to provide liquidity while optimizing its portfolio. Ethereum trades around $4,600. Glassnode reported that short-term holders realized $553 million in gains on Monday alone. Meanwhile, long-term holders remained largely inactive.
Over the past month, Ethereum gained 43%. However, profit-taking remains 39% below last month’s peak, when prices approached $3,500. Additionally, the Ethereum Foundation sold 2,795 ETH as prices reached yearly highs. The sales totaled $12.7 million, reducing the Foundation’s holdings to 99.9 ETH.
ETH Price Outlook and Institutional Interest
Some investors remain bullish. BitMEX founder Arthur Hayes repurchased $10.5 million worth of ETH just a week after selling it. Trader Yashasedu expects ETH to reach $8,600 if Bitcoin hits $150,000. Historically, ETH’s market cap has reached 30–35% of Bitcoin’s.
Ethereum’s total value locked (TVL) exceeded $90 billion. Institutional interest also increased. On Monday, spot ETH ETFs recorded $1.01 billion in net inflows. BitMine Immersion Technologies announced plans to raise $20 billion for ETH purchases.

These movements show that short-term profit-taking and institutional buying rise together. Thus, short-term sales increase market liquidity, while institutional inflows support long-term growth.
