Bitcoin is really cool. Sure, there's arguments to be made about whether it's a useful technology, whether we're currently in a cryptocurrency bubble or if the governance problems that it's currently facing will ever be resolved.. But on a purely technical level, the mystical Satoshi Nakamoto created an impressive technology.

Unfortunately, while there's a lot of resources out there that give high level explanations of how Bitcoin works (one such resource I'd highly recommend is Anders Brownworth's fantastic blockchain visual 101 video), there isn't a whole heap of information at a lower level and, in my opinion, there's only so much you can properly grok if you're looking at the 10000 ft view.
