Sun's Ethereum (ETH) transaction activity has significantly decreased in 2025, following a peak in 2024. Over the past five years, Sun's most active trading year was 2024, but 2025 saw a sharp decline in both transaction frequency and volume. This drop is a key reason for the reduced reports of Sun's on-chain movements in the past year. From 2023 to 2025, Sun primarily engaged in a strategy of buying low and selling high. In contrast, during 2021 and 2022, although ETH was purchased at lower prices, the volume of deposits was minimal compared to withdrawals, indicating that the bulk of low-cost ETH holdings were not liquidated.
