Self upvote is OK, because if you are not convinced that your own posts deserve an upvote, who else should be then? Also I invested several ten thousand dollars in this platform, so I take the freedom to try to get back as much of my investment as possible. If you want to forbid self upvotes, this is not in light with the freedom of the blockchain, and it would be an investment killer. But we need more people investing in Hive!
Thanks for your comment. I got your point. If you invest ten thousand dollar and get nothing but only HP. In final day you will have to power down your HP and sell them. I think this is worser than self voting.
