It’s really hard to get followers organically in start & you are not a celebrity right. So you can’t expect getting followers like 1k in short time. Plus assume that someone visit your instagram profile for the first time & find out that you only have followers like 200 to 300. 

Then the person will think twice to follow your account or not. There will be only one think to that person mind why he should follow your account as others aren’t following You..

But if you have followers like 2k to 5k, The person will definitely start following assuming that there must be something great about you & your account that’s why so many users are following you.

You can only gain followers organically if your instagram post show up more often in the instagram explorer page and the only way you can do it is creating high quality visually attracting posts. 

Plus the most important part getting likes like minimum 1k to one post.

If one of your post get likes like 1k the chances of the post showing up in the instagram explorer field will be really really high. The more likes your post get, the more chances it will have.

So it’s really important to buy both followers and likes.
