Coinbase CEO Brian Armstrong pointed out three reasons why the world needs cryptocurrency: (1) Global debt, especially U.S. national debt, is growing out of control; (2) Inflation continues to erode purchasing power, and people see Bitcoin as a safe haven; (3) Public trust in the traditional financial system is declining, while cryptocurrency returns financial control to individuals. Armstrong emphasized that cryptocurrency is not just an investment tool, but the foundation for building a new financial system—a more transparent, decentralized, and fairer system.
