i am a china miner, i can tell all of you,many peopel use fgpa mining X11 coin in china.
that's why gpu miner can't get a good profitability for mining X11 coin.
the X11 COIN can't prevent fpga or asic.
X11 has been cracked by fpga at this time.
so it's not fair for gpu miner.
we must ban x11 coin
new update:
x11 coin can be mined by Scrypt ASIC at this time.that's same to maxcoin.maxcon can be mined by AntMiner
http://i62.tinypic.com/2n7qwbl.jpgmany fpge or Scrypt ASIC are mining x11,not gpu miner,for example DARKCOIN,28G NET HASH are very hard to believe
same option
