my upvote is worth $3 now, could be worth $12 after hardfork 19
steem is $1 now, so $10 steem my upvote is worth $120
right now I have 140K steem, but I project to have at least 200K steem when steem is worth $10, so my upvote would be worth $200 :), and I can upvote 10 times per day without losing voting power
