I would say that spending BTC on advertizing is a waste.  Everyone in this space already knows about DNET.  Focus on the development i.e. anon tech and this will be reflected in price and growth of userbase.  If to strengthen DNET in otherways then branding could be worked on, maybe hire CRZ (I think that's the guy who did SDC branding) or expand documentation, roadmap, website, whitepaper etc.
