Its similar but here you can send any amount you want. there is a biding time every 2.4 hours and depending on how much you sent for a post you get a % of the upvote from booster.

Was wondering the same thing about booster. Just looked it up, it's a similar concept, but slightly different methodology. Going to try it out and see what it does.

Im still testing this one to see when is good time to bid and if its better to time it on a new post or 6days old post
