I don't know where to start regarding to my reply to your comment there. 😅

1. #Ecency Points can be used to either Promote (advertise your Hive post or comment to all other Ecency users) or Boost (curate your Hive post or comment). In my case, I use Boost all of the time because I almost don't get engagement (or upvotes) from the Promote feature.
2. The Ecency team has planned to tokenize Ecency Points. In fact, the ECEN token by @ecency is already on Hive Engine, but currently has zero circulation.
3. I don't know what you exactly mean with "swappable", but I guess that if you think you can trade them for HIVE/HBD or other Hive Engine tokens, then it is allowed.

Hope my comment helped! 😀
