These coins are used mainly to send virtual gifts to creators during live streams or to support content on the platform. Users recharge by paying through available methods like cards or in-app payments, and the coins are then stored in their TikTok wallet. The process is safe and official when done through TikTok, and it helps creators earn rewards from their audience.
