I&#x27;ve run into the sentiment you&#x27;re talking about both online and IRL. It puzzles me as well.<p>Three factors come to mind:<p>1. There&#x27;s a deep-rooted idea today that money comes from the government and that everything else is a scam. Bitcoin challenges that idea.<p>2. Bitcoin refuses to die despite the predictions of just about everyone who first learns about it.<p>3. The technical underpinnings of Bitcoin are counterintuitive to say the least. That makes Bitcoin hard to understand even for the technically-oriented.<p>The combination of longevity, casual disregard for convention, and counterintuitive nature gets annoying after awhile.<p>Nor are these factors restricted to those who can&#x27;t stand Bitcoin, its users, or the idea of private money. Many of the most vocal Bitcoin advocates today went through a period of disbelief or outright hostility toward the idea.
