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.
Even signature code has been updated recently as multiple option has been implemented in the project. Investors no need to worry about to part of this crowdsale project. You can find in op trusted escrows has been involved in this project. You have lauda, in that list. Therefore, you can't find a falsification at all, so don't mind about it invest it.
