That's the main difference between the so called crypto coins and fiat money; the later is currency and the former isn't!
A currency is supported by a central government, is regulated and paired with other currencies via institutional mechanisms.
No current crypto asset comes even close to the aforementioned definition, therefore it is incorrect to talk about "cryptocurrencies".
In our economic system fiat rules supreme because it is based on commodities like gold and oil.
The main role of crypto/blockchain technologies is to create an alternative way for people to makes transactions; faster, anonymous and without paying banks fees.
But replacing fiat will require a whole new world order and that's not around the corner...
yeah, that's true but you still haven't made a clear point can that new world order exist or it cannot be done?
well, in my opinion replacing or killing cash as the topic says will take a great deal of work, and it could happen but I don't think it's as near as I think how can we deliver to the people that cryptocurrencies are better and efficient in work than other forms of payment. at the end I am hoping to see any government official that have the guts to test out crypto with the common people and see how it goes
We can all contribute to the new world order, as it was envisioned by Nakamoto and the other cypherpunks. But most people currently dealing with crypto are only concerned with profits and don't care a bit about changing the world.
That's the main problem; technology can not alter the human nature and greed/ambition is a vary natural thing.
