I keep telling myself I am going to wait until I reach 100% before I upvote again, but I already did some more upvoting today.
I'm sure there is a logical reason to upvote when you can't even give $0.00 . It might have to do with reputation. But, then, I haven't seen where reputation helps you either.
Well i'm hoping them it still provides them with steem/sbd, but the value is just worth less than $.01 so it doesn't change the reward in terms fo dollars, but is still contributing!
