This is one of the most effective methods of advertising and attracting new users to the project. I will be pleased to participate.
This is the cheapest and at the same time, effective advertising. Thanks to the developers of the project for giving us the opportunity to earn OPEX tokens and take part in the promotion of the project.
yeah, if you say cheapest or cost effective way, yes i agree, but effective advertising? these i respectfully disagree with, except that YouTube channel has millions of subscribers and viewers that tune in daily to watch those videos, otherwise other means of marketing is required to draw people's attention to the project.
