I'm not really sure what are good exchange but probably Dex listing is really good, I wanted to know what kind of projects you have? I think you should make announcement about it or promotion for more people to be aware and find possible investors for your coin. It is right that most of the exchange sites have expensive fees and strict requirements before you would be able to list your token or coin.
Dex listing is easy and convenient to use for traders because you don't need to pass some KYC or any other personal information submission. The problem here is how you will promote your project to gather enough funds to further develop it or update it to something trend nowadays like NFT coins and others. You should have a unique approach to get some investors because projects nowadays have the same strategies for their marketing. in order to become successful, you need to think of a unique style to promote and advertise your project.
