My pleasure, I'm glad you learned something from it, I hope you enjoy the first part as well.
Since Hive can be accessed through various 'front-ends' (I use PeakD, others use Hive.Blog, others still use Ecency), many front-ends offer their own 'token.' Ecency Points are one such token, awarded to users of the Ecency Front-End.
As for their uses, I'm not sure, the founder of Ecency, @good-karma likely has a post or article about it, or other fans of Ecency such as @dandays may be able to enlighten, but so far, the only thing I've done with Ecency is test it out a bit and create this Ecency Desktop Wallpaper tribute to it. Wishing you lots of fun and success here on hive! 🙏
