Business starting to snowball, want to be more Bitcoin focused

Hey. Looking for some advice and resource suggestions.

I took a punt and I bought a little bit of Bitcoin in 2016 and I’ve HODL’d despite not really understanding it a time and I did think I was going to lose it lol. I used coinbase by the way...

Now that my BTC has done well, I started to watch and learn more stuff about BTC and it doesn’t feel like gambling anymore like it did on 2016

I have most of my net worth in index funds (6 figures) and it’s surprising up 40% despite the 7% average (I know this can change next year) but “it’s time in the market” what counts as we all know, with that being said, I don’t want to dip into this fund despite the risks of it being “fiat”. I know that those 6 figures into BTC would have liberated me by now financially but easy to say that upon hindsight

I haven’t really stacked or DCA’d into my Bitcoin, it’s been idle, but now that my new business is starting to see some traction. I want to contribute to my Bitcoin stack as frequent as possible

I don’t want to have hundreds of resources to learn from, so please, tell me your one go-to:

1- Bitcoin YouTube channel to binge

2- Bitcoin book that is the go to bible

3- Bitcoin podcast

As much as contributing to my index funds is very sensible. I do feel like Bitcoin has the potential to become significant especially when the rest of the world jump on board

Also, should I contribute to coinbase or should I be using a better platform?

Thank you for suggestions and hope we all become stinky rich
