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?
