$BTC ChainCatcher news, according to CoinDesk, the Office of the Comptroller of the Currency (OCC) continues to change its previous opposition to the application of cryptocurrencies in the banking industry, issuing a letter of explanation stating that banks can buy and sell the crypto assets they custody at the request of their customers.

The latest policy statement released by the OCC on Wednesday also explicitly states that banks can outsource crypto business to third parties, including custody and execution services. As long as these activities meet the safety and soundness requirements of regulators, the OCC will grant banks more freedom in cryptocurrency.
