As for art, wikipedia defines it as:
Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas.
And Bitcoin is neither of those things, it's simply a tool for storing and transferring value online.
Kinda disagree with you. Bitcoin is a work of art. It is a resulting product of human activity. Unless you don't consider Satoshi Nakamoto a human.
Bitcoin is created by an imaginative talent expressive of technical proficiency. Bitcoin is also created by the emotional power of debunking financial institutions and has conceptual ideas of banking the unbanked.
