Coinbase urges DOJ to block state-level cryptocurrency enforcement actions

Coinbase is pushing the U.S. Department of Justice to intervene in state regulatory enforcement of cryptocurrencies. In a 14-page letter to the Justice Department on Monday, its chief legal officer, Paul Grewal, said federal officials should take action against state regulations on cryptocurrency companies and that the Justice Department should urge Congress to "step in and enact broad preemption provisions."
