Guys if 50BTC are been honest.. And i think they are... the best thing we can do is mine with them so they can earn back the BTC they owe us, and return it..
Think about it seriously... Why would one of the most profitable pools go rogue??? Doesn't make sense..  And still they are in contact..

IMO we need to just give them time and support so they can fix the issues, earn some coin, and hopefully give us the coins back.
But keep in mind if they are legit, it WILL take alot of hard work to calculate everyone's missing BTC..
