I think a case like this is very unlikely to happen, especially in a country that strictly prohibits cryptocurrencies like bitcoin. Because logically, everyone in a country like that already knows that bitcoin or cryptocurrency is prohibited, so if for example there is a problem such as being cheated (using bitcoin/crypto), it is unlikely that the case will be reported to the police. Because you can be sure, if for example a case like this is brought to the police station, the problem will become even more complicated. It could be that both those who report and those who are reported are arrested, on the grounds that they have violated the rules in that country, namely carrying out transactions using bitcoin/crypto. So for sure, in my opinion, it is impossible for anyone to report such a case in a country where bitcoin/crypto is banned, even if the person was really cheated. Because as far as I know, in the realm of bitcoin or crypto, most people choose to remain silent when they are cheated. Because if for example this was announced to other people, it would definitely be very dangerous. Because it could be that after telling people about this, there are a handful of people who have evil intentions, such as robbery. Because currently people who are involved in the world of bitcoin/crypto investment are seen as truly rich people, especially by ordinary people. So if we experience a case like this, I think it would be better to keep quiet, especially if for example in a country that still prohibits bitcoin or crypto. And the conclusion from my answer to your question, it is clear that the person who reported the case and who was reported will be fined/penalized because they have violated the rules of their country's government.
