Yes, I agree, there are many accounts now, but not all are successful. To engage in Instagram, you need to devote time to this. And the most important thing is that your content is attractive to people of all ages. For example, I shoot videos about my life and blog. Many people like to follow my life and watch what I do. It inspires them, so now that I'm famous, people subscribe to me themselves. And I don't have to spend money on advertising or subscribers. The only thing I spent money on was buying likes from real people, which positively affected my account. If you're interested, I bought them from this platform https://megafamous.com/buy-instagram-likes.
