I dont share my complete strategy.If everyone were to copy it, I not have lots of competition to deal with,
Also, I get 400+ daily followers on some accounts in specific niches. Other accounts I get 100-200 followers/day. Also keep in mind I have some accounts with 1m+ followers, so they grow even faster (around 2-5k/day).
Not all niches will be able to get that high follow rates. And the amount of followers you have, will either increase or decrease your daily followers.
