[User] Show me the top 5 users who have interacted with DApps, along with the count of distinct DApps they interacted with and their wallet addresses.

[User] This query doesn't properly show DApp interactions. Please modify it to correctly join with a table that records user-DApp interactions.

[Assistant] I notice there's no interaction table in the provided schema. Without a table recording user-DApp interactions, I cannot generate this query accurately. Would you like to see users who have wallets and DApps separately instead?

[User] You're right. Instead, show me users who have wallets but have never interacted with any DApps, along with their wallet addresses.
