Is there any legal background against bit coin cheaters,who using scam sites for cheats people..
This may be possible in other parts of the world but my country is an exception. Government made it known that anyone involved in bitcoin is doing so at his/her own risk. But I think if you have clear evidence you may be supported by the high courts of justice.
I think although bitcoin has not been given regulation though but fraud can still be given a criminal whatever the case form, you're right if you have strong evidence who did the fraud on you, I think you can report it to the police, if the file is complete, I believes the police will take legal action for fraudsters
Yes, if we have any strong evidence then we can report by providing all links to the policemen. Due to decentralisation, we can easily trace the person who has stolen our fund but one thing in coming days more features will be added to this technology.
