Skepticism --- Diego, I'm a bit skeptical about this topic. Blockchain applications and cryptocurrencies are facing increasingly more complex policy challenges, in large part as a result of how they evolved. Some of the main issues, in my assessment, are: 1. Most of the "mainstream" cryptocurrencies are not de facto used as currencies, as the majority of its use is around their investment potential; 2. The main blockchains applications have chronically failed to fulfill their promise of transitioning to eco-friendly setups (from proof of work to proof of stake); 3. The cycle of blockchain buzz and blockchain scams became too big, too strong, too quick. Nowadays one needs quite a bit of specialised knowledge to differentiate scams from legitimate ones, and I think that's a fatal flaw in the technology as a whole.

In the case of Salvador, what I gathered is that its use of Bitcoin was to incentivise it as a the main tool for money transfers to the country. So, even then, it's not necessarily being used as a day-to-day currency as much as it is a substitute to Paypal.
