The quiz will cover topics like blockchain basics, market trends, and platform features, featuring both single-choice and multiple-choice questions. In addition to the quiz, CEX.IO will host an airdrop event on Telegram, where users can earn free tokens by completing tasks such as joining groups or inviting friends. This initiative aims to enhance user engagement and knowledge about cryptocurrency.
