It's a downvote and there's currently an experiment wherein people with high Steem Power aren't supposed to vote to see what happens since upvotes by people with smaller steem power will have greater influence (greater money to be able to give upon upvoting).
What happened right now is that acidyo is a whale and he accidentally voted too much that a downvote will soon be casted to kinda lower that vote.
Welcome to Steemit!
Interesting...
Yes I am just now understanding not doing 100% on upvotes as my vote was 24 cents now its something like 11 cents
But thank you for the insight.
Just seeing the positivity all around this site! Its so amazing compared to alot of the "haters" you see on other sites
