As for Krugman and predictions, one never makes a prediction without a hearty dose of humility. Predictions are the playthings of fools. Believe me, he knows that. But predictions still produce clicks and views.
Edit-
One might liken bitcoins value through Greshams law (https://en.m.wikipedia.org/wiki/Gresham%27s_law ).
Getting access to a number of services that we currently use banks for - without using banks.
Note: my reply is about blockchains, not about bitcoin.
I've more or less given up on bitcoin and think other crypto tokens have a far better chance in the long run.
Pardon my ignorance. I see this mentioned a lot. What do you mean by frictionless payments?
> Getting access to a number of services that we currently use banks for - without using banks
What services in particular? And what's preferable about using blockchain technology for these services?
I mean in the same way as email is frictionless compared to mail: you can send all day, it arrives halfway around the globe in seconds, fees are significantly lower.
> What services in particular?
For most people? Money transfer.
> And what's preferable about using blockchain technology for these services?
AFAIK because it is a way to make this happen without having to trust a number of institutions that are rich because of the current setup and might have a huge conflict of interest.
Again: IMO this is about the technology, not about Bitcoin.
