Dorsey's influence extends to the broader fintech and cryptocurrency ecosystems. Block's Cash App allows users to buy, sell, and hold Bitcoin, and the company has invested in Bitcoin mining and Lightning Network development. Square's early support for Bitcoin helped bring mainstream attention to digital assets in the payments industry. In 2022, Block reported that Bitcoin revenue contributed a meaningful share of its total revenue growth. The company also launched TBD, an open platform for Bitcoin decentralized finance applications. These moves position Block as one of the most visible traditional finance companies engaging with Bitcoin.
