I think there are several factors that help speed this up.
I have 4500 follower IG and 1500 Twitter. My Twitter is very new though. I built them by posting high effort, high quality art I was working on every day. I engage with the community and support all the other artists like crazy. Never underestimate the power of engaging and community building. Help promote others they will help you back. Share your own progress too though, this way you can grow together and you will much faster than alone.
The other things, I put time and effort into my work. These aren’t copy cat style, derivative pieces I create. Learn to create art that has longevity and looks like a viable investment, is highly original and thought provoking, rather than a joke. There should be some strong ideas behind the work too. Whether stories or interesting themes… Make something that will engage an audience not fade into the background with everything else.
We can all help each other, just be willing to really invest time practice and learning to build yourself as an artist. Develop and refine your work into something that people cannot. Anyways I know I’m leaving stuff out, if I remember more I’ll post it here. Feel free to ask me anything about my art work or the process of things.
Oh and don’t forget something everyone seems to forget. Providing a WIP means showing in detail, the whole process behind the scenes that goes into your final work. Here is an example of what I gave Rarible in my verification submission.
