According to a report from Deep Tide Techflow on December 28, analysts expect that the world's four major banks—BNY Mellon, State Street, JPMorgan Chase, and Citi—will begin offering cryptocurrency custody services in 2025. These banks collectively manage over 12 trillion dollars in assets, and this development is anticipated to drive the mainstream adoption of the cryptocurrency industry, as well as facilitate participation in digital assets at both institutional and national levels. Analysts believe that improvements in the regulatory environment will provide these banks with a pathway to offer custody services, further promoting the legitimization of digital assets.
