That's good to know, I didn't know you could send yourself pesos and have it paid at the blue rate. The official rate for GBP/ARS is only 141 today. Is it trustworthy for large amounts though? I have a lot of maintenance work to do on my house.
Re: DNI, there is something called the DNI Extranjero but I'm a bit wary of getting one. Do you start having to file tax returns once you have a DNI? I wouldn't have to pay any income tax (I don't earn in Argentina, just spend) but
all these forms take time to fill in and I don't want another complication in my life.
Are you aware of any stored value debit cards which someone a without a DNI can get, in order to pay for things online? If these exist (like Monzo/Revolut in the UK) this may be ideal for me.
