Cryptocurrency exchanges saw a dramatic surge in trading volume during October 2025, with an overall increase of 36%. This growth was led by KuCoin, which experienced a staggering 240% jump, likely fueled by targeted campaigns to attract retail traders and the listing of popular altcoins. Bitfinex, Gate.io, and Upbit also saw notable increases in volume, driven by improved market sentiment and increased institutional interest. While overall trading activity grew across platforms, some exchanges experienced more modest gains or even declines. This divergence highlights how exchange performance can be influenced by regional trends, marketing strategies, and the assets available on each platform. 2025 saw a significant increase in CEX spot trading volume, suggesting growing market optimism and investor interest.
