An Initial Exchange Offering (IEO) is a token sale conducted directly on a centralized exchange's platform, where the exchange performs due diligence and identity verification on behalf of investors, and the model largely replaced the unregulated Initial Coin Offering (ICO) format after regulators cracked down on ICOs following the 2017 boom.
From open ICOs to exchange-run sales
After the 2017 ICO wave drew heavy regulatory scrutiny, the market shifted in early 2019 toward exchanges hosting token sales themselves. Under this model, the exchange vetted the project technically, ran know-your-customer (KYC) checks on participants, and handled the sale mechanics directly on its own platform, which gave retail buyers a layer of assumed legitimacy that open ICOs never had.
Why secondary market buyers lost money
Investors who won an IEO allocation through the exchange's lottery process often saw large gains on the token's first listing day. Buyers who instead purchased on the secondary market after listing were in a much weaker position, because most of these projects lacked genuine user adoption, and token unlock schedules soon released more supply than secondary market demand could absorb, pushing prices down over the following weeks and months.
What this history suggests about token sales generally
The pattern that emerged from 2019 IEOs generalizes to token launches of most kinds: initial access and early liquidity events tend to reward the earliest participants far more than later buyers, especially when a project has yet to show verified revenue or a sustained base of active users. Treating a listing-day price spike as an opportunity to reduce exposure, rather than as confirmation to hold through subsequent unlocks, has historically been the safer approach.
- Avoid holding speculative launchpad tokens long-term without verified protocol revenue and active on-chain daily users.
- Take some principal off the table on day-one listing spikes rather than holding through subsequent lockup expirations.
