Yes the owner of cryptocoinbank pool has sold his miner to recoup losses but not walked away and still has the free 10 GH miner, cryptocoinbank pool has 1/3 of the hashing power of nastypool yet in the last 24 hours Nastypool has cracked 9 blocks and cryptocoinbank pool has cracked none. Not cost effective. The game is set to just about cover the running costs, so far approx 6 BTC has been withdrawn but I bet most of this is people taking the money out they ploughed in, not coins they've earned through the game. I don't see how anyone can do anything about someone quitting a "game".
Cryptocoinbank has the 8% of the total hash power. And 2 biggest pools Zeus and Nasty has more than 50% of the total hash power. Under those conditions, results seems normal and in the long term it will be better. It is childish that Cryptocoinbank owner quits in 2 days.
