Wow his feedback is an interesting read lol. Ive not used one yet but ive seen randowhale upvote on quite a few posts adding far more than $0.30. I think he just has alot of steem and uses a percentage vote but jones420 must have 200+ accounts, all minnows with absolutely no voting power whatsoever. The silver community could set one up, send a dollar to one account we designate that we want to build into a whale and we guarantee 20 good votes on their post from our community, get 10 of them a day paying a dollar all added to steem power of the whale and in turn we get a good vote up from the whale on our posts.
