All of those new platforms PAL, LEO and others have their own bidding bot. U can exchange tokens for upvote in steem(only in steem, bots don't stake tokens). A portion of tokens send to bot are burn, rest goes to SP delegators. Value of vote is calculated from the actual price, and gives small profit, same as with other steem bidding bots.

Even DEC earned by playing Steemmonsters can be redeemed for votes.

It's nice to test it when the price is up :)
