Summary

Coinbase (NASDAQ: COIN) is the largest publicly listed cryptocurrency exchange in the United States, founded in 2012 and regulated across multiple jurisdictions. Despite its regulated status, the platform has been the subject of significant documented concerns: a May 2025 insider-enabled data breach affecting approximately 70,000 users with estimated remediation costs of $180–400 million, ongoing documented losses exceeding $300 million per year from social engineering scams targeting Coinbase users (as reported by blockchain investigator ZachXBT), a $100 million AML compliance settlement with the NYDFS in 2023, and controversies surrounding its Base Layer-2 blockchain including a disputed token launch and a contentious departure from the Optimism OP Stack ecosystem.
