Ethereum's largest holders have been actively accumulating and moving coins amid recent market fluctuations. Notably, whale addresses holding between 10,000 and 100,000 ETH have added over 800,000 coins in the past month. Additionally, an early Ethereum ICO participant, dubbed the 'ETH Millionaire,' transferred 22 ETH, with 21 ETH sent to Coinbase and 1 ETH to a new wallet. Analysts observe a potential inverse head-and-shoulders pattern on Ethereum's weekly chart, indicating a possible long-term bullish trend.
