Excellent, a great example of POS, the more Steem you own, the more you can downvote. And you lose none for downvoting, awesome. /s
Ergo, your experience. Paid downvotes might work.
actually, you lose ‘voting power’ when you do up/downvote. voting power is... kinda MP(Magic Point) in rpg game. you have to wait if VP is 0%.
yes. fixed rate of 20% daily. but even with the same percentage voting weight, users with 10 steem power and users with 1000 steem power have different effects on upvote.
