From what I heard prx players are paid around 3k USD monthly, which while it doesn't sound like much compare to any western teams, for people living in Indonesia or Malaysia it is quite alot as the normal average pay in Malaysia is 3k rm monthly, or roughly 700 USD monthly.
Correct me if I'm wrong but Indonesia should be fairly similar. Both countries cost of living is very low if u were to convert to USD, so a salary of 3k USD + price winnings ( esp PRX achievements ) is quite alot for the country they are in excluding probably Singapore.
Albeit if they were to go overseas or got picked up by rich orgs then they most definitely would get paid alot more.
