Ethereum (ETH) is on the rise, hitting a year-to-date high of $4,108 on Dec. 16. The cryptocurrency has surged 8% in the past week and 28% over the last month, now trading around $4,000, just 18% below its all-time high. A significant factor in this rally is the decreasing ETH supply on exchanges, reaching an 8.5-year low, as whales continue to accumulate. Institutional interest is also growing, with spot Ethereum ETFs seeing consistent inflows. Analysts predict ETH could reach new heights, with some setting targets as high as $15,000 by 2025.
