First of all you need to make your own content if you want your posts to be voted, in second place i see it highly strange that the value of your steems went up so little. In third and last, voting alone won't make you rich, gotta be a bit more dedicated.
Been trying to be active but the earning is still low. Not sure what is going on though. It is so strange.
It became hard indeed to earn thru posting, that's why you should try harder in making good and original content, i personally flag whoever i see with copy-paste posts.
