Of course, participation in international conferences dedicated to blockchain technology and investment in crypto projects is a very important step! I will be glad to see the project team at such events! If you participate, be sure to make a detailed photo report - it will certainly be interesting to the project community and project investors.
Such things very well affect the popularity of the project. Many projects after they take part in a large conference for another month publish participation reports and build a whole marketing company out of this.
