Hive SBI is not selling shares. You curate a target account that you want to support permanently, and it receives Hive SBI upvotes on an ongoing basis. Then you get back your curation rewards, but in the form of votes on your own account. Because it's curation, the APR is approximately the same as just curating from your own account, but there are some advantages in having better control over how much support you're giving. Also, people respond more enthusiastically to "I got you some HSBI" than they do to "I added you to my autovoter." The first they know is permanent, independent of your decisions going forward. The second you could change your mind tomorrow.
And sure, critics will say we could change our minds tomorrow too, but Hive SBI has been running the same way with no change since the origin of Hive (and has been around several years before that on the original chain).
thanks for clarification about the funcioning of Hsbi
I just hope you do a review of accounts that receive permanent voting
Crowdsourced curation is largely effective, and sponsors mostly know it's permanent (there is a partial refund policy, but it's designed to punish abuse).
We also have an abuse-report page in our Discord and we have a vote stream at https://content.hivesbi.com that shows all the Hive SBI voted content and the value of Hive SBI votes so that it's easy for even non-technical users to review our votes and report potential abuse (or decide who deserves even more support).
