My view: "crypto" is largely full of speculative bubble ponzi schemes. Bitcoin is the only true crypto asset -- there is no second best.
As to where to start learning about it, there are many good YouTube channels and podcasts that can give you the basics of bitcoin. BTC Sessions (YouTube) and The Bitcoin Podcast (Walker), The Bitcoin Way podcast, and the What Bitcoin Did podcast are some of my favorites. Robert Breedlove did a multipart podcast series with Michael Saylor on his podcast What is Money (I think it's like 10 hours).
This video is a nice introduction to the concept of bitcoin:

Fidelity has published regular pieces on bitcoin, and some of them give some general background for education on the topic:

There are some great books out there as well. "The Bitcoin Standard" is one you'll hear frequently; "Broken Money" is another.
There's even a Bitcoin Policy Institute in DC now, and I'm sure they have some information you might learn from:

I don't tell people to "buy bitcoin" -- I tell people to "learn about bitcoin" ... if you do, you'll be able to decide if you should get some.
