I can confirm Ghash is doing a double ltc reward. In other words, you make twice the money. No brainer to switch
it looks like scam
Most definitely not. I've already withdrawn LTC and can confirm I am making 200%.
This is the same provider of what was once the biggest BTC mining pool. Apparently they even became big enough to almost be capable of executing a 51% attack. The community became wary and decentralized the larger pools. Regardless, they went on to provide mining services, a trading platform, and other unique stuff.
Since they are coming a little late into the LTC mining game, it seems practical to release this kind of promotion for a lucrative company. They know miners will come.
I wonder how much of that double profit will be eaten by fees - those guys have very aggressive fee structure I think.
