In fairness to the present, the first post on HN about bitcoin[1] had 3 comments:
1) this is amazing and will save humanity
2) this is dumb no one will ever use it
3) this is confusing
That ratio doesn’t seem that much different than recent posts.
I think you’re right that most people at least on HN have decided what they believe when it comes to bitcoin.
Ultimately money is a belief and not just any belief but one so central to our identities that we often organize our lives around how we can get enough money.
Strong beliefs get tied into our identities so that threats to those beliefs will be viewed as many as attacks on their identities.
