i think ghost.zeuspool.com has an error.
when you click on pool you can see how many ghc people mine with how many kh/s they have, but i think they forget the block rewards halving.
for example someone with 2500kh/s on zeuspool gets 100000 ghostcoin/day
on ghc.hasing.at with 2500kh/s is 70000 ghostcoins/day
so it looks like you get more coins when you mine on zeuspool, but its the opposite, you get more coins at ghc.hashing.at
I've mined couple of other coins and they rip you off big time. Was thinking about mining this coin with such a low difficulty, but none of the pools seem to be good. The official pool is not connecting at all and the only other option i see is zeuspool and I prefer to stay away from them.
