The advantage of Zelle is that unlike Visa, it is a dollarization tool. A Venezuelan merchant can directly earn U.S. currency.
The ones that do manage to get any savings will rush to the black markets to convert bolivars to USD or EUR. The ones that don't get any savings are SOL.
As someone who grew up with 30%-40% inflation a month, I find it really weird to see someone thinking any of that is cool.
Is cool that they do it, as it allows more payment methods to then and allows me to spend my USD, the more formal the business is, the more it will avoid using informal payments methods like zelle, so I do use my US creditcards in big chains, etc. As for every other aspect of our economy, im clearly hugely affected by it, me saying that POS taking usd cards is cool, doesnt mean i agree to our mess of an economy
I don't know if you miss the point that the official currency of venezuela is still the VES, and business have to still use VES for so many reasons, yes a big part of the VES gets exchange to USD but the main currency, still the VES
And yes, I understand that the economy is not de jure dollarized, so that there are still the need for bolivars at some point. My point though is that having a parallel, USD-pegged economy outside of the "official" markets would be better for the people than not having it.
I suspect a side benefit of dollarization is being able to avoid to declaring income. I doubt they are paying taxes in the USA either.
