A major U.S. banking institution with $2 trillion in assets has begun accepting Bitcoin as collateral for loans—marking a pivotal shift in how Wall Street views digital assets. This move signals growing institutional confidence in crypto's legitimacy as a financial asset class. The implications are substantial: when legacy financial players start integrating Bitcoin into their lending frameworks, it reshapes perceptions around crypto volatility and store-of-value properties. For the broader ecosystem, this represents a breakthrough moment where traditional finance and decentralized finance find common ground. Whether this becomes a template for other major banks remains to be seen, but the precedent matters.
