I disagree @slobberchops. There is and should be no harm to the community if the user earn rewards via posting/upvotes and sells the reward on the exchanges. It is the right of the investors/authors. This is how the system is build and this is how it should be. What is wrong is the 15% and recently years of 20% APR on HBD which caused massive sell pressure on hive build-up over the years.
The whales have also been causing damage to the platform by posting and participating in the spam "Burn posts" and "Burn comments" to get curation rewards which they could have got instead by upvoting quality content. But they want it mostly to keep for themselves. 3% APR on HP is also hurting the platform as investor get free money for doing nothing productive for the platform.
The community needs to focus on growth to add value to the platform, remove the ridiculously high HBD APR also HP APR.
