No offense - don't you think that the article contradicts itself?
Seriously !
Look - what is a stablecoin? This is a CRYPTOCURRENCY, with a hard link to.. FIAT! Yes Yes ! Exactly. Not by the power of its network, not by the number of tokens, not by the number of wallets, and not even by technology. FIATOM!
And what will happen to "stablecoins" if fiat currencies "disappear" tomorrow? It is logical - and stablecoins will disappear, since they will not have real collateral! And they are called "stablecoins" precisely because they do not have wild volatility like classic cryptocurrencies, based, today, solely on speculation! And this is provided by fiat "reserves" or liabilities.
And now back to what you probably didn't guess. Yes, there is let the development of STATE currencies which is called CBDC. But this is not anonymous, "independent cryptocurrency"! This is a new level of fiat! Now it’s clear why you shouldn’t rejoice and shout “Goodbye fiat, long live CBDC”?
This is the same thing, but not the stablecoin you expect. This is a digital fiat with an even more global control and management mechanism!
