I know a few hundred dollars here and there doesn't sound like a lot, but if you are doing it while living in a country with a favorable exchange rate (say, Brazil or Argentina), it becomes an easy way to earn a decent living. I've done it myself.

Even with favorable exchange rates, living in most metropolitan areas in Brazil is very expensive and you are likely to earn more working for Brazilian clients - right now unemployment is under 4% in general and almost inexistent in IT so wages are up.

The situation in Argentina is good if you get paid in cash because the black market pays twice the official (and artificial) rate. I guess it is not so good if you are being paid through a prepaid card like payoneer.

I assume you mean PPP ratio.

While PPP is probably most important exchange rates matter too. Most people tend to bid/pay in USD. So for me when the GBP/USD was right I could charge the same as usual in USD but that translated to more money in GBP.
