user5068: I couldn't find the specifics on how would one get more coins with PoS.
I understand that with PoW one gets more coins by having more hashing power and running software like cgminer.
With PoS, I need to have more coins, and… what else? Just have the client open? If that's the case, it's kind of risky, isn't it? I mean I would have to have my private keys in an online machine?

user14400: Yes, you have to have client with all your coins open with your private keys and have it sitting on online machine.
