Is there some countries police investigating this fraud? Or is that a crime without risk?
You can try to report to your police department, but I doubt this will get your money back. What I advised to all victims of this Electrum
hack is to try unite and jointly attempt to do something to try to find this hacker/s.
Just recently one research is show that over 800
BTC is stolen, but that number is probably much bigger and constantly would increase. At current price it is $10000000 if we asume amount is close to 1000
BTC. Individual cases probably do not interest anyone, but a group lawsuit against an unknown person or criminal organizations would definitely make sense.
But considering how things stand in crypto world, you are probably right, this is "crime without risk".
