User base may not be as high as Ethereum but it's still growing. Most are probably just staking at the moment and waiting for the potential they see on Cardano.

I don't see this chain losing relevance despite Ethereum's recent updates. It's true that we don't hear much about them since developers prefer the slow and steady approach. Only releasing new features when they are certain it's ready for mass usage. The chain seem stable unlike others that has outages every now and then. Perhaps that's also one reason why it remains in the top 10.
