Hey I want to share my experience in creating a new account from scratch and bring it to 50K in just 3 months I couldn't believe it was possible either since I have not yet formed a certain topic of content direction and etc but I started using a service that allows to
get auto comment on your instagram posts which in turn displays your photos and videos in the tops and recommended. I haven't fully understood the whole algorithm yet and how it works but it works and really promotes your account. So with full confidence I can advise it.
