MVP built, SEO done recently(to an extent) what next to get an audience?

I have been working on a product to track live cryptocurrency prices across different exchanges in INDIA. I have created an MVP (https://www.cryptocost.in/) and recently applied some Search Engine Optimizations (sitemap.xml, lighthouse report suggestions, GSC, bing webmaster). How should I market the product apart from SEO?. I have not been able to get significant traffic on my website. Also, I am thinking to bring charts and some analysis tools to the website. Should I wait for the audience or continue building the product?
