mintpal doesn't give info what the "attack" exactly was. How were funds stolen? Their hotwallet? A 51%-attack/doublespent? We don't get that info. All we know is: mintpal claims to have been "attacked" and there will be a rollback.
If the story of the attack is true or not or what exactly happend: we don't know.
This is a problem right here. Just because it's stolen does not mean they should be able to arbitrarily reverse the hack. If they're successful at hard forking, this will set precedence that any time there is a theft reported, devs can just hard fork again. This will eventually be abused, and corruption happens.
+1
just their hotwallet hacked doesn't justify a rollback. They should eat that bill and care about security. An attack on the coin itself? Where is the info? I am not satisfied with the info we are getting here!
