Circle has assembled crypto's first vertically integrated financial stack: USDC dominates stablecoins (64% volume), USYC leads tokenized treasuries ($2.2B AUM), and activity-based yield regulations reward the model by design. The architecture creates compounding network effects that regulation reinforces rather than threatens.
