Congratulations on your new HSBI 😎
25 HSBI Units is considered monthly post support whereas 50 is weekly and 100 is daily.
You can sponsor other accounts and each HIVE sponsored gives 1:1 HSBI.
One for you and one for me from the sponsorship mentioned on this post.
Be careful though because this is HIVE that you will not get back except through the rewards of your content.
