The "future of money revolution" is
one user story. It offers a place to express angst in monetary policy, no different than startup founders talking about disrupting whatever, it's the same wave. It offers some utility in that regard and is still growing at a noteworthy pace. (capital is bypassing bitcoin and going straight into stablecoins which settle on bitcoin and ether. bitcoin and ether are becoming primarily used as fuel. check the marketcap growth of stablecoins over the last 6 months, it is new capital.)
I completely understand how to hold seizure-free assets, some of that involves the discretion of a judge with cash and physical property held in trust's name, some of that involves the permissionless nature of crypto, stored properly. Its just a tool and it's actually pretty okay at what it does.
In other areas, 10 years ago I couldn't convert an international wire transfer into a domestic wire transfer, now I can and it avoids greater compliance scrutiny and speed, while retaining unlimited amounts, and inherits same day settlement. (corporate transaction another country paid in crypto, converted to fiat in local bank, transferred to local brokerage account, 6-7 figures or higher.)
Without crypto, I as of recently have transferwise and now Revolut to do the same thing, which both have an extremely long list of unsupported businesses and transfer limits that are pretty decent but not as good.
There is a slower regulatory process of making any of this practical, which is still happening, such as the processes that allowed Kraken to get that bank charter. Wyoming's laws were passed in 2018, went into force 2019, and Kraken was in regulatory approval since then. On the federal level, of OCC just gave its gracings to national banks to custody digital assets, this year! This will be challenged, primarily by Wyoming lobbyists, who wants Congress to make that order or not. Only Bitcoin has risk management financial products, not even Ethereum yet, in 2020.
There is also a large market of customers in the crypto arena, and high margin business models that don't require that many customers in order to book 7 figures of revenue.
