IDO marketing campaigns are designed to capture investor attention through storytelling, community hype, and pre-sale exclusivity. Tactics include influencer outreach, AMAs, airdrops, and social media contests. Projects also create scarcity by offering whitelist spots or limited access passes. These activities, combined with a transparent roadmap and working product demos, increase investor confidence. By building a strong online presence and providing early rewards, IDO marketing campaigns can quickly attract both retail and whale investors.
