This is my short story with, so have you ever used bitcoin as a means of payment for the purchase of physical assets like land or anything else?
No, I will not violate the regulations set by the government. So you shouldn't tell anyone how you use bitcoin as a means of payment in a country that prohibits it as a currency. Especially Indonesia, I emphasize that your actions are violations and you have violated them. So don't do it if you know it's banned because you end up risking a penalty.
There is only one way that is highly recommended if you have bitcoin and want to pay for something in Indonesia, you have to convert it to fiat and make payments safely without dealing with the law. This is the best advice from me, so never deal with the government especially if it is related to money. They can freeze your account and confiscate your assets.
