I have used @randowhale, @discordia, @booster, @minnowbooster and @bellyrub is cool also!
You have also @drotto that only requires 0.001 SBD for an upvote and will not give you much eheheh
What I try to do before using whalevotes is to go look for theire voting power and send the SBD to the one with the biggest voting power!
Peace, Carlos
