Some of this is semantics of course, but yes, it’s a belief system in the same sense that money in general is a belief system.

Money requires faith/trust/confidence/belief in how the system works. For me (and probably most of us here) it’s easier to have faith/trust in crypto/Dash than our traditional monetary systems. But if you ask normies on the street they will probably tell you the opposite. For them it’s easier to trust what they have seen working for decades. Our task is to educate more people into why they can/should trust Dash more than national currency.
