TikTok is a great place to join in on viral challenges. When a new song comes out, people make their own versions of the challenge and use hashtags to share it and get on the app's main page. If you want to be featured, it's essential to have many followers. Growing your following on TikTok takes time, but if you want a shortcut, you can buy followers. However, buying followers is only sometimes the best way to build an authentic community.
