There are so many ways to promote that dApp or the ethereum. If you want to encourage that here, you should give some details about that so we will be able to know what are things in that application. It would be better for the things that you are promoting if you give some information that we can read on that. I suggest that the best way to push that thing is on social media. Social media are internet services that let you interact with others and share and create content through online communities. Social media present great marketing opportunities for businesses of all sizes. You can use social media to promote the name of your brand and business, and there are so many users of social media, including all of the person here in this platform, so if you use social media for promoting dApp, I will assure you that it will be known from many people around the world. The best thing about social media is that when you post something and when a person finds it so attractive, then he might share it too as well, so by that many people will know that information.
