"This is my 9-to-5 job," Nader, who said he makes between $1,000 and $12,000 per month as a creator, told CNBC. "This is what I do to make a living. This is how I pay for my groceries. This is how millions of small businesses make their money."

Nader's new reality, however, is far from stable. TikTok, which is owned by China's ByteDance, is nearing a Jan. 19 deadline by which it has to be sold, or it faces a ban in the U.S. Like many other creators who have come to rely on TikTok, Nader has been urging his fans to find him on other social media apps before he potentially loses them altogether and the substantial income stream that they represent.
