I see this Project doesn't use regulary promotions to attract investors, hoping the NVO crowdsale will succeed soon
I do not know what type of regular promotion are you looking for but as of May 19, 2017, NVO has a signature campaign here in the forum. I believe that this is a regular type of promotion that undoubtedly attracts investors. Not just the advertisement via signature campaign but also the project itself attract investors.
Just found a big banner on coinmarketcap. Check it out. Is that enough promotion for you?
