I'd recommend everyone change their passwords on coinmarket to a new NEVER used one, complex asap Just as a precaution that is - we don't know what happened & will have to wait until the site admin to say but my best guess is a pool operator using stolen login creds.
I'd hate to see more coin fall into the hands of a thief.
Please also share TXid's so we can keep an eye on the movement of the stolen coin.
all pretty sad, all does guys were mining for those coins, and putting their on money in it. Yes, never use the same passwords on different sites, as they know your username, and they try to login and they steal it. And for a pool operator it is very easy to know who he need to try, the guys that can earn a lot of coins and then moving downwards. Really sad, this should be a great day for KDC!!!! and honestly people losing money is not what we want...
