Brazil's government-run payments system has become dominant

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)

Try to use cryptocurrency for anything other than a few very specific transactions at a number of places in the world so small that it's a rounding error.

And somehow less relevant than cash.

I can take cash from any country in the world to my local bank, and deposit it into my account. I can get a dozen different foreign currencies at my local branch in minutes, and almost any other currency in the world can be delivered to me by FedEx the next morning for a flat $10 fee.

I can take cash to any other country in the world and get it converted into the local currency, whether that's paper or digital in almost any city.

Crypto is great if you do a very few, very specific things in a vanishingly small number of places. But if I'd tied my finances to crypto instead of cash, I'd have been stuck many times in foreign lands.

If you are at a institution bank, probably but that's a non-existent use case - I never had Argentinian Pesos, Turkish Lira or Bulgarian Lev I suddenly needed to deposit into my bank account !..

I'm not sure whether you travel much, but I always travel as a digital nomad. I pay small transactions with local cash or mostly bank cards as everybody does. But big amounts? That's where crypto comes into play. I've paid in crypto transactions worth a few thousands dollars because that's the only way to do it without incurring huge transaction fees and / or long processing time.
