The U.S. Securities and Exchange Commission spent 2018 cracking down on cryptocurrency and cybersecurity issues, according to a new report.

Gibson, Dunn & Crutcher’s 2018 Year-End Securities Enforcement Update said the federal agency focused strongly on cryptocurrency and digital asset regulations last year. That’s in part because of crypto’s popularity, media coverage and fluctuating value in 2018, said Mark Schonfeld, the co-chairman of Gibson Dunn’s securities enforcement practice group.
