Sounds to me like they have absolutely no clue what they're talking about. They forgot to factor in that the internet created the phenomena of fake news, and soon crypto will create the phenomena of fake money. When that happens, next stop is a mass exodus from national fiat into crypto. There will be as many popular cryptos as there are currently fiat currencies and they will be able to do atomic swaps between them.
Their old models for financial prediction will not work in the new world. As a result, authority will be blindsided. Eventually this ends with the collapse of most national fiat currencies.
I think they are actually predicting something along those lines actually. If you read the report they very strongly favor coins that are either a store of value, offer privacy, or are used as a currency. The ones that can be built on top of didn't grade well in their eyes.
I read the report all the way through, but I don't agree with it. For one thing the estimated market cap by 2028 of 3.6T is drastically low. By then, the internet of money will be the dominant form of banking and the banks that survived will be subservient to crypto. Or we will have a digital panopticon and crypto assets will be a centralized version of bitcoin with high speed networks (aka Fed coin).
They don't seem to understand that the main use case of bitcoin as a SOV is not going to be the dominant use case of even the dominant form of money in the future. The uses of EOS, ETH and other smart contract platforms are going to be the most dominant because they will be used in hospitals, corporate infrastructure, manufacturing and logistics, and will replace many aspects of current governance. Simple P2P value transfer as bitcoin is merely scratches the surface.
The speed at which this is happening suggests the first hiccups to global control will happen by fall 2022 and depending upon whether we fall down the path of a digital panopticon we could then have a generation of pain following thereafter until it's understood by the population that centralized IT doesn't work and is DANGEROUS.
If we're lucky and don't fall down into Amazon becoming a one world government that controls everything with the new constitution based on "social media credit" then decentralization will cause governments to collapse everywhere along with national fiat. When the other 6 billion unbanked people of the world jump the USD petrodollar ship, it will be game over.
It's certainly possible. All we can do is wait and watch with some popcorn. :)
