My selection: Reddit. If users click from a subreddit and are aligned with Ecency's value proposition, it means their interest is genuine. These users will not only see the ad, but they will also be much more inclined to explore the platform, understand it, and sign up. On YouTube or Facebook, from my perspective, people are usually in “entertainment mode” or “social mode,” and we would have to convince them from scratch that Ecency is worthwhile by taking them away from their main intention. On Reddit, however, they are already in “discovery mode” or “niche mode,” which would be perfect for Ecency.

This is the first thing that came to mind. Since Ecency is geared toward valuing quality content, niche communities, and Web3, it requires an audience that already has an interest in or understanding of the aforementioned concepts or is actively seeking out these types of topics or platforms.
