I can tell you why crypto is so popular in Russia
Don't know about Indonesia (but the same reasons can apply there as well), but in Russia people are very suspicious of the local government (deep inside) up to a point where they can publicly tell you one thing (e.g. that they fully support whatever the government does) but in reality they definitely know better (read, they don't trust the Russian ruble). And crypto happens to efficiently and effectively end the government control over personal finance enforced via inflation and a multitude of other nasty devices (given the rich history of fiat devaluations and money expropriations in this country)
Different from in Indonesia, there may be some of the same reasons for each user. but most people here support bitcoin and crypto because of the economic benefits they get. I myself still believe in the government, and my local currency, I support bitcoin because I get a lot of benefits from it
Almost every country with cryptocurrency adoption seems to have the same stand on cryptocurrency usage. No country has officially revealed support for Cryptocurrency usage, but there isn't no big opposition from the government which is the one that makes a outlook that bitcoin is supported by some countries. India has opposed bitcoin and now there is some positive news after the G20 meet.
