Self-votes, not really a good investment

Hi friends,

I've been thinking on the amount of SBD and STEEM that is spend everyday in self-votes, if the bidder decides to lease SP instead of doing self votes and then voting all his followers posts and comments, I'm 100% sure he will make more SP in return than invested plus will make a lot of people grow and then maybe they can lease more SP and give back some love.

This is my first though after reading this post I guess everyone is getting thw wrong STEEM investment perspective. I've stopped using those services for self-voting. I'm relying on my followers and the good will services.

My point here, is that 1 SBD vote for 1.5 SBD worth of rewards is not a good investment. with about 1 STEEM you can lease about 40 SP and that will increase your vote power to at least 0.001, if you do lots of upvotes, comments and posts you will increase payouts and curation rewards. My goal is to increase SP so I can do more voting, but will get me SP in return, so why pay for a upvote? when I believe you can invest in getting SP for lease and will do a better investment in the long run.

Not sure if this is how it works, but I rather increase my SP.
What do you think about this?
