I suggest modifying the "Popular Evaluation" tab as it doesn't have a valid source. Anyone can just put a full star rating on any of those bounties. Instead, you can collect data from various ICO checkers and analyzers and take their average rating for reference.

But honestly, since bounty hunting is not that active as before, I doubt someone will consider using a list from a new source. I hope you will able to gather more visitors as the site progress.

P.S Much better if you will consider putting the donation/tip address at the bottom part of the page. It currently messing up with the main content in my own view.
