Coinbase shared big news Monday that federal regulators are allowing the popular cryptocurrency exchange to proceed with plans to sell cryptocurrency tokens that are deemed securities.

Last month, Coinbase acquired Keystone Capital, a California-based FINRA-registered broker-dealer that operates as an alternative trading system. With the announcement, the SF-based cryptocurrency exchange disclosed that it would still need to get regulatory approval to operate under the Keystone licenses.
