It means the pump in dogecoin using this tiktok will not last long. And if some countries ban the tiktok then the dogecoin will dump again because tiktok will have a big impact to the users like dogecoin. Doing such strategy to pump a coin is a great idea but the problem is the result and the impact of it someday.
Why would someone Dogecoin dump if they have no access to tiktok? The hype of Dogecoin was caused by tiktok. But nobody needs tiktok to buy or sell Dogecoin.
