You're right about the distinction. When goods are priced in fiat, 1 BTC's purchasing power fluctuates (sometimes buying a car, sometimes a house). But priced in sats, 1 BTC always equals exactly 100,000,000 sats. That's Bitcoin's true constant. The challenge is that most of the economy still operates on fiat pricing, creating a practical dilemma: pricing purely in sats means missing most potential sales. So we default to fiat pricing with floating BTC conversion. We're seeing this evolve in stages: from early BTC pricing to today's hybrid model where merchants display fiat prices but accept BTC, to emerging Bitcoin-native communities that think only in sats. The psychological barrier is real. Humans have always been struggling with rapidly changing price references. Nostr and Lightning Network are helping by making sats practical for microtransactions. When you can buy a coffee for 10,000 sats without mentally converting to fiat, that's when the real paradigm shift begins. Unfortunately merchants don't arbitrarily price in sats as they tend to respond to customer demand. The design challenge here is to create a user experience so seamless that it naturally builds this demand: - reducing friction with instant LN payments - using psychological incentives like satoshi discounts - creating exclusive sats-only products or services - making the tech invisible to empower users (they are not early adopters) - (add your idea here) The pricetag strategy succeeds when the user experience makes paying in sats feel more natural and beneficial than fiat alternatives, thereby creating the very demand that makes satoshi pricing viable.
