How do I update myself about Bitcoin? What resources should I use?

I’ve been learning about Bitcoin for the last week and I’m hooked.

I always hated, banks, government, IMF, big pharma, big food, big financial markets, regulators, lobbyists and academics (when I say academics I mean the people that are perceived as specialists, but, they are there because the lobbyists put them there and are paying them to tell what they want)

Bitcoin is FREEDOM!

I know the basics of how it works and what can be done with it.

Now, I need to update myself about the new tech around Bitcoin. I heard about layer 2 payments and so forward.

Where do I learn about this?
