Predicting the exact time for an airdrop token’s exchange listing requires careful monitoring. Follow the project's roadmap and social media for any announcements related to exchange partnerships. Additionally, participate in community discussions on platforms like Telegram and Discord, where updates about listings are often shared. Keep an eye on smaller exchanges, as some tokens first list there before expanding to major platforms. A surge in social media buzz or market interest can also signal an upcoming listing, so staying engaged in the community is key.
