@ Cecep Sunarya:
- … If it is discovered, can I be imprisoned?
No. The government does block many commodity futures trading (broker) websites from abroad that are considered illegal, and also blocks websites of gambling games disguised as trading, but so far there have been no sanctions. If fraud etc. occurs, the losses are borne by yourself.
Answer to Cecep Sunarya: No, so far the government's action has only been to ban and block illegal broker sites from abroad.
