I'd be surprised if this turned out to be a scam to be honest but the way it's been handled doesn't look good. They set a date and then claimed they'd been attacked, judging by the money that was invested into this ICO, i'm not surprised. I have a minor investment into Electroneum and just hope they're true to their word that they're improving the platform with Amazon and Hackerone. I'm sure if it wasnt true, hackerone would of denied it by now!
