Score 23/30. 1.75B mobile-money users; 5M active at $2K/yr, 50 bps = $50M ARR. Tech stack only assembled in last 6 months (Cashu CDK Swift/Kotlin, Spark SDK, Fedi one-click federation, BOLT12). Capital solves what killed Mutiny ($800K). No proven PMF for ecash wallets yet (100K active is the threshold). Competition fierce (Strike, Cash App, Wallet of Satoshi via Spark).
