Not impressive right now, but better than nothing I suppose.
Thank you, that answered my question. I was gonna stake abour 3 btc worth of ppc and see what I come out with. Don't seem it would be worth putting thtat much coin up for low return.
Well, PoS minting is not worth letting a PC run 24/7 for most people. It's worth it, when you either have 100-200k+ PPC or the PC would run anyway.
But: As tacotime suggested, you could wait for your coins to gather maximum coinage (90 days) and the run the wallet for a few days. You will generate lots of block in these days. Than wait for 90 days again and repeat. You won't gather that much PoS as you would running the wallet 24/7, but it's much more effective.
Edit: AND you help to protect the network when you are mining PoS blocks. That's a big benefit for me.
