At the beginning of 2018, many did not understand the principle of operation and the purpose of stable coins. Now, I think, our explanations are no longer needed, because there are already more than three hundred different stable coins, and information about them can be found everywhere. After the scandals with the advent of the stable coin Libra, national stable coins of various states should now appear in large numbers. Now the entire population of the Earth will soon know about stable coins, in any case, at least their own state.
I think we should distinguish between stablecoins and state/government's currencies being put on the blockchain.
The latter are nothing but the same old fiat money, just circulating on the blockchain.
At first it circulated hand to hand (paper).
Then it circulated electronically (on line).
Now on blockchain.
This is no real innovation, under monetary perspective.
It's the old, same, fake fiat money, controlled by the central banks.
Private stablecoins, that's the real deal.
This is the monetary revolution.
