I was cheated in speculating in foreign exchange. Is it useful to call the police?
It's hard to say whether it's useful to report after being cheated. However, there should be no better solution than reporting the case. If a report is made, the police will file a case for investigation. If you can solve the case and arrest the suspect, your cheated property will be recovered. On the other hand, if you don't call the police, there is no chance of recovery.
