I don't know how young are you, but I have seen worst economic situations in my country that even topple a dictatorship. Worst, after 30 years, the country is still in financial crisis and dollars per local fiat is rising.

I can't say what would be the economic fate of Indonesia because as neighbor nations, I wish that everything will not be in chaos (might be a coup-d-etat, new government form but then the problem still persists), and I guess the sitting government should do everything at their power to avert another financial crisis. If your question is, will this affect crypto? I will say no, it wouldn't put a significant dent on the price, but Indonesians can run to crypto to leverage their wealth until the government find a way to prevent the disaster.
