I can´t understand the hype, I mean why Dogecoin? Is there a specific reason to it beside that someone called out a challenge? I´m not sure if a pump-and-dump on Dogecoin is a good way top represent cryptos on a social network. As for TikTik itself, people will use VPNs and continue using it, even though that will decrease their user base significantly.
As I know people just joking and get used to using Dogecoins for memes or other funny things because the movements can be said only go up once a year. People just want something different and want a significant movement, we know doge was formed long enough.
