So, what's the easiest way to become popular on instagram? I want to find a prospective niche but have no idea at this point so any suggestions would be appreciated.
It depends on you and your account. You can always post body pictures and get a lot of likes like many girls do. If you are not hot or you are a man, you can buy some likes on https://www.igautolike.com/ and attract people with your deep soul and wit. LOL
