Securities lawsuits filed over either cryptocurrencies or bitcoin have tripled so far this year as U.S. Securities and Exchange Commission chairman Jay Clayton announced a crackdown on that industry, according to a new report by legal analytics firm Lex Machina.

Released on Tuesday, the report found there were 45 cases filed so far this year that mentioned “blockchain,” “cryptocurrency” or “bitcoin” in the filings, up from 15 in 2017. And the SEC, which has vowed to scrutinize cryptocurrencies and initial coin offerings (ICOs), was responsible for 30 percent of the cases filed in 2018, according to Laura Hopkins, legal data expert at Lex Machina, a unit of LexisNexis. That’s the second-most popular filer of such cases, topped only by the law firm Levi & Korsinsky, she said.
