Moving Power for Cryptos Dominance?

So, couple of guys (Marek and Lukasz) from "Policy Department A" prepared a report for European Parliament’s Committee on Economic and Monetary Affairs. Members of that Committee are intend to use the report's data during some discussions later in July. 

What caught my attention (there were no sacral truth report to be fair) - is a bold statement claiming that "despite their technological advances and global reach, virtual currencies are far from being able to challenge the dominant position of sovereign currencies and the monetary policies of central banks..."

And the authors of the paper only suggest the possibility of crypto becoming a major mean of monetary relations in "individual economies"  in extreme cases, like "war". 

 I find European Parliament's folks report quite arrogant. But it made wonder: 

What's your thoughts on moving power for cryptos dominance? 

My vote is for real case use of digital currencies (like PundiX) 

or simple to use infrastructural projects, "grandma's crypto wallets" etc. I think it's right around the corner.
