I wanna learn some more about Bitcoin, but I'm running out of things that really catch my interest. What are things one should know and read-up on about Bitcoin? I have a rudimentary understanding of how Bitcoin works, and would like to dig deeper about the possible implications that a widespread usage of Bitcoin could have in the far future, as well as how and why people can, or should engage with it today.

What topics do you reckon as being important to know about?
