Tiktok already lost 200 million users since when India banned them from their country and now America is most likely to ban them as well so this is going to get nagative impact on the project and do you really think people spending time on Toktok ever thought about investing? 
Not just with that. It's now exposed that they've been hiding a spyware and various articles have been made for that to let the other knows who are not great with Cyber Security. I hope that many people will stop using TikTok because of what it really has. But I like the idea of Dogecoin challenge but we can always do that even without TikTok.
