Ethereum ( ETH ) has been operating within a multi-month rising channel since its low of $1,300 four months ago, with a weekly rise of 21% to $4,275, approaching the historical peak of $4,800 from four years ago. The strong upward momentum is driven by continuous institutional buying, as the Coinbase premium index shows a significant influx of capital into the U.S., with a mysterious institution purchasing 220,000 ETH in a week (worth $946 million). However, concerns about high leverage in the market are emerging, with the estimated leverage ratio across all exchanges ( ELR ) reaching 0.68, close to historical highs, warning of potential increased bidirectional price fluctuations. Although buyers are dominant, pushing ETH to potentially test $4,501/$4,788, caution is needed as a breach of the key support level at $3,980 could trigger a wave of long order liquidations.
