Exactly, marketing is the most important part for promising projects to become a success, because if no one knows about your great offer no one will use it! And the big advantage of new and good ICOs is that the price is very low and if it will succeed you can make a very huge profit of 20x and much more like it already happened with several other ICO projects.
We have to understand that the coin's success depends on us, promoters the most. Than higher interest we will attract than higher price we will get in the final, and it's all in our interests.
