Adoption isn't El Salvador's government mandate or corporate treasury purchases. Real adoption is a grandmother in Argentina using stablecoins to escape 200% inflation, a remittance worker in Philippines saving 7% on wire fees, a merchant in Lagos accepting payment in hours instead of days. We imagine hockey-stick charts and mainstream headlines; the actual pattern is friction reduction in places where the existing system already failed. That's where the next billion users come from, not from convincing people who already have working banks.
