I have heard a lot of people say and believe that "if your product or service is good, it would sell itself". That's not entirely true.
Yes, a good project selling itself is no longer the situation in a broad market where there are already a lot of good projects that have already gained huge traction, especially in the cryptocurrency where there's already a lot of competition in the market, and the best thing a new project will do to get the needed attention if doing the right marketing and listing on good liquidity provider exchange. This is what the team of the SUI project did despite the project's unique concept.
