Trading volumes for major cryptocurrencies, including Ethereum and Bitcoin, have reached yearly lows as 2025 comes to a close, according to Santiment data. Altcoins such as Solana, Cardano, and Dogecoin are also experiencing reduced activity. This decline in transaction volume contrasts sharply with the previous year's holiday season, suggesting a potential for extended sideways market movement and sudden price fluctuations. Analysts anticipate a possible recovery in trading volumes in early January, contingent on Bitcoin's performance.
