it looks normal when NVC more valuable as LTC but i think PPC is better than NVC as it uses SHA which is less power consumer ..
Is SHA really a lower power consumer than scrypt? I guess per hash it is, but there seems to be a lot more network power going into SHA than scrypt... i.e. Bitcoin.
No but PoS uses less power then PoW. The only problem for me is that it generates coins based on a interest model. When I got into Bitcoin, I was so happy this coin is generated without interest, but ppc unfortunately does use interest, generating coins if you hold a lot of coins (this is my understanding of PoS) I do not like interest and that's why I do not own any PoS coins like ppc nvc or cgb.
