It's also worth point out the report is talking about blockchain, and not about cryptocurrency. In fact, it doesn't mention cryptocurrencies at all, outside of a single brief mention of bitcoin:
I think that's the main distinction that you have to look for.
I personally think that Cisco, being the company that they are, are mostly providing an outlook for institutional or corporate blockchains as opposed to cryptocurrencies. The context is most likely more so about data, accounting, private transactions in businesses etc. than decentralised blockchains as a means to store currencies.
It's an interesting forecast and outlook for the many applications of blockchain tech, of course, but I definitely think that this is a lot less relevant in terms of bitcoin's market capitalisation or market share in the global currency markets, than the title makes it seem like.
