Initial Coin Offerings (ICOs) peaked as crypto’s dominant fundraising mechanism during the 2017 boom, and while their specific format has become far less common since, the underlying need for crypto projects to raise capital hasn’t gone away.
Key Takeaways
- Regulatory scrutiny has significantly reduced the prevalence of the classic, minimally-regulated ICO format.
- Successor models like IEOs and IDOs emerged partly in response to ICOs’ fraud and accountability problems.
- Private funding rounds have become a more common path for many projects.
- Airdrops and points-based distribution models have, in some cases, replaced traditional fundraising sales.
- Regulatory clarity continues to shape which fundraising models are practically viable.
Our Take
The evolution away from the classic ICO format reflects a broader maturation pattern common to new financial technologies: rapid innovation, followed by regulatory response, followed by adaptation.
What’s genuinely interesting about the successor models is how differently they distribute risk — private funding rounds concentrate early-stage risk among sophisticated investors, while retroactive airdrops reward demonstrated usage after the fact.
