I just found a website which will show you how much your Upvote is worth! What is more you can check there who and when Upvote your post, and much more.
Window in the upper left shows your statistic and worth of your vote.
On the right side are your daily curations and authors rewards
Below that is window with Upvotes given to you.
If you like this post, Upvote it or leave a comment! Thanks ;)
