Of course, you can! But the question is do you have what it takes to stand up against these villains? Lol. I called them villain cause thats what they deserve to be called. You can take legal action against them, if you know who they are. Its possible.
Even you do not know they could be traced down by the police once the complaint is officially launched. They have a cyber cell team who can trace them and put them behind the bars if the need be or depend upon the crime or theft they have done. One should go and register the complain if you have being cheated.
i think its imposible to traced someone who uses bitcoin because we all know that bitcoin is kinda anonymous and private , although it is posible to view and linked their bitcoin addreses but criminals and hackers were too smart to be caught. They may be even use a fake bitcoin wallet/address and fake profile in order to hide thier identity. Overall it is really hard to trace and caught bitcoin cheaters or hackers rather we can only avoid them.
