Despite the rising DEX-to-CEX ratio, centralized exchanges still lead in the crypto spot market, posting $3.9 trillion in trading volume, compared to $877 billion for DEXs.
Cryptocurrency traders have been moving away from centralized exchanges (CEXs) in favor of decentralized exchanges (DEXs), pushing the CEX-to-DEX ratio to a new all-time high.
Spot trading volume on DEXs surged at least 25% in the second quarter of 2025 over the previous quarter, while CEXs volumes plunged almost 28%, according to the latest quarterly industry report by the crypto data aggregator CoinGecko.
This shift drove the DEX-to-CEX ratio to a record high in Q2, rising from 0.13 in the previous quarter to 0.23, the report noted.
