B2B dominates at $226B (~58% of $390B total annualized stablecoin volume), dwarfing C2C ($77B), C2B ($76B), and B2C ($11B).

Opportunity: B2C optimization. What if seamless UX closes the B2C gap? It could ignite a retail flywheel, reframing stablecoins from B2B rails to everyday currency beyond current narratives.(unfolded.)
