A strong community is the most important aspect of being successful with your token. Everything else is just a tool to build that said community.
A strong community is the backbone of any project to stay relevant in the cryptocurrency market, without it there is no better way to build trust and get new investors to buy it. Where to list your token should be when you're ready to kickoff the project officially otherwise it will just be another failed project that got listed. Developers should research and find out the reasons why there are many failed projects in the crypto space to avoid making their mistakes, they should define a use case that can benefit the crypto community so that they can remain relevant instead of just launching their projects and scamming gullible investors.
