Best resources to learn Crypto / Bitcoin from scratch? (A to Z guide)

I want to dive deep into crypto and Bitcoin, but honestly, the sheer amount of info out there is pretty overwhelming. Most of the stuff I run into online feels either way too technical to understand or just ends up being a sketchy sales pitch/shill for some random coin.

Does anyone have a solid list of go-to resources, websites, or video series that cover everything from the absolute basics to the more advanced stuff? I'm just looking for unbiased, A-to-Z guides that actually break down how it all works without the fluff.

Appreciate any links or recommendations you can throw my way!
