They is so many rumours this is one big well organised scam.
Where?
it's obvious, nobody with half a brain would mine coins they can't withdraw which means most of the hash is dev and his group mining most coins, and when you have most coins you have absolute control , this will be a dump fest . good luck
its possible, dev can redirect hash to mine darkcoin for example, but did u see another X11 coin that has jump in network hash rate?
They may point them to several X11 switching pools. If anyone is so dumb to get on this scam, he would at least check difficulty in sgminer once a while to see whether it is +/- stable..
