What Is an ICO? Token Sales, and What the 2017 Wave Demonstrated

The mechanism

A team publishes a document describing what they intend to build and a token that will be used inside it. Buyers send funds to an address and receive tokens in return, before any product exists. If the project succeeds and the token is genuinely needed, early buyers hold something useful. If it does not, they hold a token.

What made this possible was the absence of a gatekeeper. Raising money from the public normally requires registration, disclosure and liability for what you claimed. A token sale conducted on a blockchain, to buyers anywhere, sidestepped all of it, briefly.

What 2017 showed

Enormous sums were raised on documents. Projects with no working code, no named team and in some cases plagiarised whitepapers took in millions, occasionally within minutes. The bar was not low; there was no bar, and the market demonstrated exactly what it does under that condition.

Regulators responded by applying existing securities law: if you sell an instrument to the public on the expectation of profit from someone else's efforts, the label on it does not change what it is. Public token sales largely stopped, enforcement actions ran for years, and the practice migrated into forms with more structure.

Where it went

Into launchpads that gate participation, private rounds followed by a public listing, and airdrops that distribute tokens for using a protocol rather than for money. Each version changes who buys first and on what terms, and each keeps the essential feature: a token distributed before the thing it is meant to be used for is proven.

The most useful lens on any of them is supply. Who received tokens, at what price, and when can they sell. A private round at a fraction of the public price, unlocking six months after listing, tells you more about the likely price path than any part of the roadmap.

Reading a token distribution

Four numbers describe most of what matters. How much of the supply the team and early investors hold, at what price they received it, when it unlocks, and how much is circulating on day one. Together they tell you who is positioned to sell into whatever demand the listing creates.

A distribution where insiders hold most of the supply at a fraction of the public price, with unlocks beginning within months, is not hidden information. It is usually published in the documentation, and it predicts the shape of the first year better than anything written about the technology.

Where the money went, mechanically

A sale collected funds into an address and issued tokens in return, and the part worth understanding is what happened next, because it explains most of the failures better than any account of intent.

Raised funds were usually held in the asset they were raised in. A project that collected during a rise and did not convert was holding an asset that could fall by most of its value before anything was built, which turned a budget into a market position nobody had chosen to take. Several projects that intended to deliver simply ran out of runway this way.

The second mechanism was liquidity. Tokens sold to early buyers at a discount arrived on exchanges alongside a much smaller float, so the price was set by whoever was trading a fraction of the supply while the larger holdings waited. That structure produces a strong opening and persistent selling pressure afterwards, independent of whether the project was any good. Neither of these requires bad faith to explain a bad outcome, which is why reading the funding structure told you more than reading the whitepaper did.

What has actually improved since

Disclosure norms, mostly by force. Documentation now routinely covers vesting and supply because buyers learned to ask, and platforms that gate participation apply at least some filter. That is real progress from a market that had none.

What has not changed is the basic asymmetry. Someone is selling a token before the thing it is for exists, and the reasons to buy remain projections. Better paperwork around that arrangement makes it more legible without making it a different arrangement.
