So I have been using Instagram for a while now but pretty much for only for my personal account. (With a few short lived accounts) I am looking for some help with choosing a niche for an account I am looking to make. I am pretty much open to any ideas but I want to know what grows the fastest. I am also looking for some tips on how to grow my follower base quickly. I have heard of hashtags and a little about bots but I'd like to know the most effective method to grow fast. (Preferably free).
