I have been crunching the numbers and for me to even get to a 1000SP target I need about 800 SBD.
Yet I am motivated to do it because of all the minnows I am helping out in @steemitfamilyph in getting them confident and writing good articles and not vote begging or using one of the five tags as the name of a whale.
To make them quality STEEMIANS who will further enrich the community with their content.

Start of the year I got an 800 delegation from @blocktrades because I wanted to make a little
more difference from being able to upvote 10 people a day because of my low SP I can now upvote a lot more and even reward very good content with a full vote which merits .41 cents at full power. Very small compared to dolphins and whales but to us Minnows (I don't think I am a minnow yet) is a huge difference.

Let's face it there are just too many material out there for a handful of whales to notice and with all the votebegging they get its so hard to filter through the noise.
So it does make sense to delegate some of those vests to dolphins and even minnows who are trying to get involved and enrich the content of the Steemit community.

It is admirable that a lot of the whales you mentioned are doing that and you for that matter have done really well in mentoring people and empowering them to be a good part of this community.

Always a pleasure reading your thoughts and giving hope to people.
