Coinbase acquired Keystone Capital a little over a month ago. Today the security and Exchange Commission announced that Coinbase has the approval to operate under the Keystone Capital License. This license allows Coinbase to sell securities.
In the past Coinbase was limited to currencies like Bitcoin, Litecoin, Bitcoin Cash, and Ethereum. The popular platform will now be able to sell a wider variety of coins. Coinbase has announced that they will be adding other coins. A few of the coins being considered include Cardano, Stellar Lumens, Ox, Zcash, and Basic Attention Tokes (BAT).
