I'm once bitten, twice shy after this myself, and while the PASO voting intention surveys ≠ what will happen (let alone the election itself and a ballotage scenario), the idea that Milei isn't a frontrunner is kind of silly as he at the very least has been polling in first place.remember that trump won. everyone has a chance
Regarding dollarization, things will be on fire for probably the first year as people adjust, but as Ronnie said, Milei comes with other problems as he wants to eliminate social plans and fundamentally change the makeup of the Argentine state which will plunge even more people in to poverty.
As to the original question, people with dollars will be fine, just like they are now.
