Initial Coin Offering (ICO)

In an ICO, a project sells newly created tokens directly to the public, usually in exchange for Bitcoin, Ether or stablecoins, in order to fund development before the underlying network or product even exists. Buyers typically rely on a project's whitepaper rather than audited financials, which is what makes the model both fast and risky.

The format traces back to Mastercoin's 2013 sale and Ethereum's 2014 token sale, which raised roughly $18 million and helped popularize the approach. ICOs exploded during 2017 and early 2018, when projects collectively raised billions of dollars in a matter of months, often with little more than a website and a roadmap. That boom ended abruptly once regulators intervened: the U.S. Securities and Exchange Commission ruled in its 2017 DAO Report that many tokens qualified as unregistered securities, and later actions against projects like Telegram's TON, Block.One (EOS) and Tezos resulted in large fines, refunds or canceled launches.

Since then, ICOs have largely given way to more structured alternatives, such as exchange-vetted IEOs and on-chain IDOs, though ICOs still occur in less-regulated markets. Modern issuers increasingly build in KYC/AML checks and try to structure tokens as genuine utility tokens rather than investment contracts, partly to satisfy frameworks like the EU's MiCA regulation.

Key risks remain unchanged: no refund guarantee, no operational product at sale time, and a long history of exit scams and abandoned projects.
