Any prediction of the peso/dollar exchange rate at the end of 2020 will be influenced by who wins the US presidential election. This influence will be enormous. If Trump wins, the dollar will probably strengthen around 15%. If Biden wins, the dollar will probably weaken about 30%. These ranges are not limited to the peso/dollar. They will also control for the dollar against pretty much every foreign currency.
Just a reminder, now is a great time to take all the dollars you have and convert them into pesos. It appears likely that Biden will win and the dollar will weaken 30% against the Argentine Peso in the upcoming year.
You can thank The Donald for your nice 30% return.
