It was when I learned it was actually decentralized and had strong forces that would keep it that way, and not decentralized-in-theory¹ like nearly everything else that calls itself decentralized these days.

Before that, I mostly saw it as another "blockchain" and was interested in the tech. Then when I started learning about "blockchain" through bitcoin, I had this aha and it brought back all my memories of austrian econ that I'd given up on for practical reasons.
