I tried the Ghash for a few hours and pulled my rigs back to my normal server. They don't really have enough hash power to find blocks of Doge and litecoin to make them worth it. With more hashpower to get the pool moving it looks promising I really like the features they offer with keeping the coins to swapping to btc or ltc.
I've been running on there for almost 24 hours now... Will have to do a little calculation once I start seeing payouts. I've got right about 2MH on there so I'll give it 2-3 days and see what my daily rate looks like and compare to this chart here to see if its worth it.
If nothing else, its an easy way to pick one or two coins and get autopayouts in LTC or BTC.
