I’ve been down the Adsense route and decided to get off of it. Aside from the fact that it will ruin the look of the site, and just turning you into a data mining point - The pay was abysmal for the work put into getting 10k users a month. It’s hard work trying to go subreddits and self promoting whilst risking getting banned.
I think this site is giving users some value that stock portals are not. I’d say keep shaping the product till you capture as much value from the big guys. Then hopefully a better idea for monetizing will crop up from this journey.
