Also add in that when you have a high level account you tend to relax a bit more and create less posts. This is an opportunity for smaller accounts to be more active on the platform and make some serious gains. Since you can outwork and level up.
Hard and smart work will never get old. Keep being hungry in life that's the key since most lose their hunger after a while. Finding new ways to motivate yourself and become excited since losing the passion and engagement is what mess most people up in the long run.
I agree @phoneinf.
Smaller accounts need to post, post, and post more.
That is what will shift these numbers even more.
The whales cannot post enough to keep up with all the newer posts that go up.
