There is an other whale who upvote minnows as well, he support good quality posts, I've got from him a good upvote twice wirth about $50 when the price of steem was higher, he is @yoo1900 . You can take a look at what he is doing, he gives 5 big upvote to minnows everyday. There is also @surpassinggoogle , he is also very active and he upvotes a lot of people and support them.

But of course there are a lot of whales that don't even use their power, it's really sad while people are working so hard but don't recieve the support they deserve. I think it will be good if developers just give away that non used power to minnows or to communities like dtubedaily, onelovedtube, dcooperation and others.
