Bullshit. The El Salvador bill (and even the various El Salvador govt reps - or peeps directly involved in discussing the direction of such developments) have not said anything about the "adoption of blockchain-based cryptocurrencies".. at least not so far.. Maybe you need to show me such a link if such a thing exists?
That sounds like your dumbass wishful-thinking interpretive way of framing the matter of what is going on in hope that you or some other dweeb can pump some kind of stupid-ass shitcoins, put out lame and misleading talking points or other nonsense.
Thankfully this is about bitcoin, not garbage altcoins or the little side projects from the institutions that are destined either shrink or disappear entirely.
Sadly these types are common here, talking about "ecosystem" which is euphemism for altcoins which most (all) reproduce the same flaws of fiat or worse.
The politicians and some media people in my country love the word "cryptocurrencies" its no wonder we have the worst economy of the planet. Bitcoin is no mere cryptocurrency or "something blockchain", Bitcoin is the reason the world is changing, not a blockchain or flawed clones and blockchain less tokens.
Its not about cryptocurrencies, its about Bitcoin. It matters, because the others do not follow the same principles and simply confuse or worse.
