No matter how good a project is, it needs good marketing. It is only when one is aware of your product that he can attest that it is quality. That is why we have the saying, "it's better to have a bad product with a good marketer than a good product with a bad marketer"
For marketing that will not cost you much, I recommend reaching out telegram and other social media and consult influencers with much followers. It always give result but the charge may be high, I personally use my friends so it costs me less.
Secondly, consider a referral system. This system works like magic. Spare that little percentage and make more.
OP is Last Active on 16 March 2022, I don't think he's interested in any suggestions here anymore.
he did not even take part in further discussion, so I'm not sure how sincerely he wanted to hear advice from the community. I guess he just expected to just get some spectacular strategy that hasn't been used yet.
Newbies are known for not replying or following up conversations they started. It doesn't really mean that OP is not sincere about his question. It will be nice to drop as many as possible answers. He can always visit this thread and have them when need be.
