Dev team failed hard on the launch, that much is fact. The attacks began happening before the early close of the ICO, at about $30million raised. At this point they should have been working their asses off to correct the issue for a successful launch. I'm sure the reason the attacks occurred was because they bragged about it being secure, however I had to enter an email address and password for signup, no confirmation or anything required. Many accounts have been noted as multiples, which means the number of registered users could be highly inaccurate and may not have the most registered users in ICO history; and we may never know the real numbers.
Now I agree that hiring hacker one is a good move...if they actually hired them....wouldn't mind seeing an official statement from hacker one that they are working with Electroneum.
I personally feel that all trading with ETN should be suspended until the issues are resolved, as currently the only people that are able to sell their tokens are miners, or people that bought on the exchange. This has resulted in a lot of the community gaining a distrust for the devs and ETN. The result will be a dump on the market if & when the ICO coins are released. Furthermore how many newbies to crypto will be scared away by this course of events. Poor communication by the team, lack of viable information when communications are released, and too many delays. The longer it is the less confidence new users will have in cryptocurrencies.
Honestly this could have been handled much more effectively, but now so many investors feel screwed over, and this will likely turn out to be good only for miners.
Half way into ico should have given them signal about tighten up securities, the number of members on telegram was insanely increasing by minutes yet they refuses to see warning signs to secure investors funds, that was so unprofessional of the team the their various acclaimed professional background, now investors have to suffer the long wait and hope the teams can get their act together.
