Great post, upvoted and resteemed. @booster seems to be not effective at all, it returning half of the value (0.27 vs 0.5). If you count curation, then it is will be around 0.22. I recommend not to use booster right now due to high count of bidding. However, @randowhale is quite effective, since it has halved the cost from 1 SBD to 0.5 sbd.
