It is happening but what goes around comes around, the STEEM investment becomes value to your posts somehot.
Onw time I waited for @randowhale voting power to ebcome 100%, I still got only 4% upvote. Whereas I saw on one post it got 48% upvote. But I still use @randowhale upvote when I have 2 STEEM in my wallet. Otherwise I just use minnowsupport on Discord.
