The California company -- the fifth licensed to trade in digital currencies in New York -- now will be able to offer Ethereum and Litecoin as well as "Shift Card," Coinbase's virtual-currency debit card service, the state's Department of Financial Services said in a statement.
The announcement also spotlighted tensions between the agency and national banking regulators in Washington over who has the authority to oversee the so-called fintech industry dealing in virtual currencies.

"DFS has proven that the state regulatory system is the best way to supervise and cultivate a thriving Fintech industry, like virtual currency," DFS Superintendent Maria Vullo said in the statement today.
