$600 on $100 = + 600% not 60%...however no one who invested in the ICO has received any of their coins with an unsubstantiated report of an attack. It doesn't surprise me since the team behind Electroneum are marketing ppl, spinning a yarn is how they make their money...for investors in the ICO the current state of affairs profit = -100% and with the amount of coins out there and people eager to take a profit I think you would be getting off lightly if that figure rises to 0%
