Brazil's government-run payments system has become dominant

I've been living in Brazil for the last 20 years.

Pix revolutionised the way we transact in Brazil. I've used Pix to pay for things that cost only cents, and I have a friend who bought her house using Pix. The system just works for any transfer amount. And it's so easy to use.

Its speed is truly baffling, and so is its reliability. Never have I failed to make a Pix payment because of downtime. I never cease to be amazed by how fast money arrives in my Brazilian account when I make a withdrawal directly from my EUR wallet on Wise. I receive a push notification from my Brazilian bank before Wise finishes running the animation of confirmation of withdrawal. It's like magic.

And it's so widespread that nowadays I don't even question whether someone accepts Pix. When I get in a taxi, no matter how old the driver is, it's certain that they take (and prefer) Pix.

I've even had homeless people ask me for Pix instead of change on multiple occasions.

Cryptocurrencies don't stand a chance.

Now, try to use Pix outside of Brazil - it's not even used in other Mercosur countries, what's the chance of having that adopted in other countries... And, that's problem #1.

How much do you trust your government with your money? A system like Pix don't stand a chance to get a worldwide adoption - maybe people are naive but governments won't unify to adopt a common system controlled by just a single entity / country.

What we may however end up with, are dozens of systems like Pix, one for each country, union, etc. Still cryptocurrencies as-is remain relevant (see point 1)

80 countries have instant/real time payment systems today [1], and the Bank for International Settlements is working on cross border interoperability [2].

Cryptocurrencies will likely never go away, and will remain in use for certain use cases from a cross border value transfer perspective, similar to gold; either the token moves or the ownership is updated. More interesting is offering digital wallets for a single or basket of currencies to anyone you can remotely identity proof in the world (similar to nsave [3]).

On top of that, the BIS isnt even needed for global real time payments. A company like Wise (formerly transferwise) or any similar entity can just hold accounts in each country and if the local settlement is real time they can also do real time global settlement by just updating their db and sending the money real time in the receiving location.
