the same purchase on one of the exchanges would have helped to raise the price of steem.
The choice to transfer it onto the platform would have had no further effect.
If he's just an investor who has decided to support only one person with his SP, that is his right. When that sole support inflates the payout to that individual, it is the right of other whales to counter that support through downvotes.
Even though the size of the upvote is determined by his SP, the value of the upvote is coming from the reward pool which is formed from the collective mining (posting values) of the whole community.
Allowed to go on unchecked that would mean one whale could disperse a significant amount of the reward pool to one individual rather than it dispersed throughout the community as the system is meant to do.
When whales are upvoting posts, they generally go with a small percentage of their VP so they can spread it across a wider number of posts.
Interesting to note that we all have 10 full upvotes a day that we can make and have our VP recharge within 24 hours. @haejin's posts never exceeded that magic number. HMMM
My last comment basically covered this
To that end, the simplest answer to the @ranchorelaxo saga, is that he may have profited from the advice of @haejin and chose to show his appreciation through upvoting.
It also seems as if he did not act overly irresponsibly and has since curbed the behavior. Lets assume he made $500,000 and upvoted @haejin 10% of his profit. Not unreasonable...
We will have to see how it plays out...
