just spent 50 hive sponsoring 5 people using Hive Basic Income. the people that were chosen are Hive account@mengao, Hive account@samuelvelizsk8, Hive account@brunodias631, Hive account@albuslucimus, and Hive account@rama-dev.
Hive basic Income Units determine how much Hive account@steembasicincome will upvote your blog posts. when you send to them using this tool https://peakd.com/@stoken.quest/wallet/others
(attaches a username to the memo) YOU and the person you sent to, get 1:1 of the Hive Basic Income Units, equal to the amount of hive you sent. so each person got 10 HBI units and Hive account@stoken.quest got 50.
here is the website for it.
