Dodge - 1110 GH/s
Syscoin - 894 GH/s
Viacoin - 887 GH/s
This can be merge mined with litecoin, so you are wrong.
The hardware in this coins is the same as in litecoin.
You can't hide so much hashrate in altcoins.
... You're kidding, right?
Yes, Hardware is the same. They all using the Scrypt algorithm.
But NO, they can NOT be merged..
Syscoin is worth 275,378 USD (market cap)
So how much USD you can mine/time? Calculate it and then say me why should anyone point 894GH of hardware to this worthless coin? Do you think you just have to increase hashrate to a coin and you get more reward with every machine? Sorry, then you have to do some research.
Coins generated per day * Coin value = max. reward/day
You would probably buy a x million USD farm to mine for a coin that can max. generate some hundred $$$ a day
