Using Ethereum

Hi All,

This is my first post on this subreddit. I have been following this subreddit for a week now and have mined 0.2 ETH so far. I am trying to think of what to use it for. Any ideas ?

One cool usecase I saw is the ENS registrar (https://ens.domains/). It is a decentralized name registrar. Are there use cases in production that you know of ?
