My difficulty is, at heart, I don't want my tokens of exchange to be a product at all. I want the guarantee of universality that comes with money. Accessible to rich and poor alike, good credit or bad. Anything that tries to edge that out via the market is inherently a bad thing. Ultimately for all except stockholders. A central bank backed cryptocurrency with all the traits of universality and legal tender may be a better bet...

I am fully in favour of the various new banking services and apps that are springing up, services to manage, transfer, save and invest better etc. That's an appropriate place for the market. Even there it's needed regulation to ensure the most marginal in society can get a basic bank account, or not get stiffed on fees.
