The Bitcoin Standard is a book to read. I think understanding money is very important. Then dive into self custody and how to actually own the asset yourself. There are some jobs in bitcoin; it’s a new space in all honesty but it’s getting there slowly.

I have a YouTube channel which may benefit you - I also do AMAs on my streams so if you have any questions feel free to ask.

Also, I don’t really think any paid courses are needed - education is free online. What you could pay for is the finer details when you’ve loaded yourself with knowledge that’s available freely.

Anyways feel free to check out my channel, it’s web3, Bitcoin, self custody and cybsersecurity based. Just one big note - it’s a new space so there’s a lot of scammers out there. Don’t ever share your seed phrases, or just listen to random people. So some research and find out the legitimacy of people / influencers.
