A significant move by Ethereum whales has sparked concerns about market volatility. Following a brief crypto market rebound, these large investors transferred over $213 million worth of Ethereum to Coinbase in two separate transactions. This activity comes despite the price surge for Ethereum which saw it reach a new all-time high of $4,656. Despite the gains, the transfers have been viewed as potential warning signs due to their timing and previous patterns. Experts point out that such large deposits to exchanges are often associated with sell pressure from institutional investors or high-net-worth traders, as they seek to secure profits during periods of market volatility.
