Vote bots are pretty lame, I don't really see the point over all. I just take the "spam" approach of making videos and blog posts like 123021397123 times a day and hope people notice, and so far I've gotten one whale vote in about 6 months, which isn't too bad. I also invest a lot myself, but there's not much content on steemit that I also like (video games, speedrunning specifically) so I don't really interact with many people here other than myself as a result :P
