For me it was a bit of both. I already leaned towards libertarianism, free markets, and a suspicion of centralized authority. This made me very open to Bitcoin's value proposition from the beginning.
But delving into Bitcoin also exposed me to even more Austrian thought, and in particular it motivated me to read up more on the history of money, and I became even more convinced, as well as educated about the issues.
It doesn't hurt that during this time (2020-2021), governments were engaged in some of the most rapid monetary expansion ever seen, leading to ridiculous inflation, while at the same time engaging in some of the most authoritarian actions against their own citizens that I've seen in my life.
