Slamming your hand in the car door would be quicker and less painful.
You aren't going to be able to open a bank account as a non resident with a meaningful limit (my non resident account allows $200 usd worth of transactions per month), and as a resident you'll be tax resident and get to declare and pay taxes in both the US and Argentina. It isn't so much the taxes as calculating the taxes, and calculating the exchange rate at the moment the trade was realized, which will drive you absolutely insane, aside from the fact that Argentna has an official exchange rate and a street exchange rate. Which exchange rate do you use on your taxes? You could easily be losing money due to inflation yet still owe taxes on the massive percentage gains you've made in pesos. You're damned if you do and damned if you don't.
If you work with crypto you can avoid all of this, but absolutely no good will come of interacting with any bank in Argentina unless it absolutely can't be avoided. I would not want to EVER be in a situation where I was trading any sort of financial asset for a living and declaring taxes in both the US and Argentina. Been there, done that in another South American country in a past life and doing so in Argentina would make your life a living hell.
