The answer to the question is that both Ethereum and EOS are quite active when it comes to development, and their respective decentralized exchanges (dexes) are more liquid than other chains. Ethereum has been around for longer and has a larger developer community, and its dexes have become increasingly liquid over time. EOS is a newer chain, but its dexes are also quite liquid, with some of the most popular EOS-based tokens having high liquidity. Both Ethereum and EOS have seen significant growth over the past few years, and their respective dexes have been a major factor in their success.
