The Bank of America patent explains:

"Enterprises may handle a large number of financial transactions on a daily basis. As technology advances, financial transactions involving cryptocurrency have become more common. For some enterprises, it may be desirable to aggregate cryptocurrency deposited by customers in an enterprise account."
