What should be the nature of links that are pointing towards your money site?

I am getting a lot of suggestions about this. So, I am asking here in this forum. Many people suggest relevant anchor texts, contextual links, links from PBN's, links from high quality Web 2.0 sites. But what I want to know is that what should be the nature of those links??!! Fully optimized, moderately optimized or no-optimization at all.
