Hive Steem Basic Income.
If you own units of HSBI you can get your post voted by one of the SBI accounts.
The more HSBI units you have, the more you get voted. Currently you need around 20 units to get a vote of 0,02USD every other day.
You may have noticed that I said unit and not token because it is not a tradable token. You need to be sponsored for your first unit and after that you can only earn unit while sponsoring someone else or being sponsored (it is forbidden to sponsor yourself).
1 unit is obtained by sending 1 Hive to SBI, it is also possible to get units by delegating HP to their account.
You can find the doc on their website if you want to read more !
