Getting smart on crypto/blockchain/web3 in 30 min per day

I’m not new to crypto, have a technical background, know the basic concepts and have been around for a couple of years.

What is your recommendation for deepening my knowledge on crypto/blockchain/web3 if I were to dedicate 30 minutes a day to it?

Is it a news outlet? An online course? A book? Something else?

No specific target here - just want to stay current on the biggest topics and learn along the way, so let’s say a year from now I feel a lot smarter and experienced on crypto/blockchain/web3 than I do now.

Thanks!
