That seems to be effective for that exchange, I can't think of what exchange was that as I've watched it on YouTube. And as for Eterbase, this is another incident that will make most of the exchanges not to stop being aware of the hacking and those hackers never stop penetrating and stealing exchanges fund.
This is big warning for traders and investors to not store their coins in any exchange, I hope it's not an inside job and they recover the funds and catch the hackers but it's going to be very hard, they need the cooperation of other exchange to track all those stolen coins, this has been the issue of so many exchange, it's a 24 hour business of exchange to keep their exchange fully secure hackers are always watching for a flaw.
The only hope that they can do is those hackers will wrongly send it to the exchanges to sell it which they've alerted already.
