Well .. How did you register to MercadoPago? I never was able when I was in Argentina (end of last year). It also asked me for some official IDs in Argentina which is even harder to get than a CPF (or probably impossible as a non-resident, I didn't bother at that point)

With MP you need an official ID, but there are some crypto apps that have pix and allow to register with a passport.
