The report is big and slow to load, but read the part regarding digital currencies, starting on page 18.
An interesting bit:
Conventional credit/debit card payers transacted about $15.5 trillion in 2013, and the major credit/debit/payments firms have a market cap of more than $300 billion. Bitcoin transactions have potential cost advantages over conventional payments and reduce the need for intermediation. The gap between conventional transactions cost and any Bitcoin fees for convenience and increased security will allow Bitcoin to make incursions into this market. For investors, the question is how much of this gap will be eroded by competition, with the majority benefit going to consumers.
