I remember the first years of bitcoin's life. There were so many things to do and learn: mining, faucets, wallets, blockchain visualizations, etc.

Nowadays the bitcoin world is pretty boring: mining is for people with deep pockets, faucets don't exist anymore, wallets are getting centralized by big corporations (blockchain.com, coinbase, etc.).

Is there anything fun left to do with bitcoin, any specific application, website, app, anything that will make bitcoin fun and interesting again? Otherwise I just keep on holding and that's it.
