I think bot must needed minnows like me .. i spend 4 hours creating a post and i earned 2 cents for that at the same time i have seen some one just post a meme earned $4 i was confused then i talked to one of senior steemian explain to me how bot system work.
And i believe it's good for steemit too because whatever you earn from steemit you reinvest it again. It add more market value to steemit. Just my opinion tho.thanks
