I believe the greatest story behind Brazil's Pix, India's UPI and Kenya's Mpesa is the emergence of a lot new forms of money.

We will have strong national currencies supported by these payment systems, destroying Visa and Mastercard and hurting PayPal, Apple Pay and Google Pay. These systems have a lot more potential than most people imagine (e.g.: micro lending , even for illiterate people).

We will have "gangster money", a.k.a. crypto currencies, to sustain illegal activities. There is no other use case for crypto, only this.

And we will probably have "economic blocs" money (e.g.: whatever thing the BRICS come up with).

In this scenario I'd hope for a big change in the international payments system.

The dollar will not have one rival, will have many. I hope it dies by a thousand cuts.

One of the key benefits of India’s UPI is that it’s removed the middle man when it comes to benefits to the poor which has drastically reduced corruption and ensured the money goes to the people it’s supposed to.

The West likes to paint the government success in India around religious terms, but in reality, it’s the actual improvement in life driven significantly by the adoption of UPI that’s played the biggest role.

About Pix, I think people forget really how useful it can be to different things.

You can sign documents with Pix! ClickSign and others support it. You can just send 1 cent, and this can be one of the possibilities to sign documents!

I'm sorry but last few months have done nothing if not demonstrate the need for crypto currency, aka digital cash. It may not be ready, but it is likely the only path forward. In the meantime Monero is relatively stable, sufficiently anonymous, and has comparatively low transaction fees.

The monopoly of existing payment processors cannot continue. They have a stranglehold on fees and issue cards that promote economically harmful activities. They and contactless payment processors sell your data. And now they control what you can and can't purchase.

Enter national digital currencies such as as the proposed CBDC. Fear-mongering sites making such outlandish claims [1]. So I do a bit of research, and find [2]... wait, what?

"In addition, it [full anonymity] would make it virtually impossible to limit the use of the digital euro as a form of investment – a limitation that is essential from a financial stability perspective."

Suddenly I trust [3] so much less. The technical controls required to implement inventory limits would just as easily enable expiration dates and automatic devaluation, or whatever overreach governments deem necessary down their slippery slope.

Where does Pix fall in this spectrum?

I find it interesting your very narrow view of cryptocurrencies given the things you're excited about.

Don't let the bad shit (and, holy shit, there is a lot) distract from the potential.
