Born in January 2014, she was diagnosed with cerebral palsy and doctors warned her parents that she might never be able to speak. To help their daughter through her diagnosis, her mum and dad started a YouTube channel for her where they encouraged her to speak, walk and enjoy herself.
The following year her parents, who ran a bridal salon and a construction company, sold both businesses to invest in their daughter's YouTube channel, surviving off family savings until Nastya's channel began to turn a profit. Eventually Radzinskaya's cerebral palsy was reviewed and deemed a misdiagnosis.
But the family continued with the channel and watched in delight as their viewers grew and grew.
Over the course of a single year, 107 million subscribers across seven channels signed up for Nastya content.
By 2019, Forbes had noted Nastya as "one of the world's fastest-growing creators, thanks to videos in seven languages".
Two years ago In 2020, Nastya sold the rights to her old YouTube videos to Spotter.
According to The Sun, she has kept the rights to new content and, along with her earnings from the Spotter deal, has also amassed her fortune by way of brand deals, a merchandise line and an NFT collection.
Now, alongside her parents, Nastya runs several YouTube channels which when combined make her the biggest child YouTuber in the world.
