Crypto projects have raised billions of dollars through token sales, but the way they launch new cryptocurrencies has changed significantly over the past decade. While Initial Coin Offerings (ICOs) dominated the 2017 crypto boom, today’s projects may combine private funding rounds, presales, community sales, IDOs, IEOs, and other token distribution methods before or around their Token Generation Event (TGE).

Each fundraising method offers a different balance of accessibility, liquidity, and risk. Some allow anyone to participate, while others are limited to early investors or users who meet specific eligibility requirements. The launch model also influences how tokens are distributed, when they become tradable, and whether investors face vesting schedules or token lockups.

Understanding these differences can help investors evaluate new crypto projects before committing funds. In this guide, we explain how crypto presales, ICOs, IDOs, IEOs, and fair launches work, where they overlap, and the main differences investors should understand in 2026.

Why Crypto Projects Raise Funds

Building a blockchain project requires significant funding long before a token begins trading on an exchange. Development teams need capital to write and audit smart contracts, build products, hire employees, market their platforms, and cover legal and operational costs.

Many projects raise funds by selling rights to a portion of their token supply before the token becomes publicly tradable. In return, participants receive tokens either immediately or after the project's TGE, depending on the terms of the sale. Early investors often receive lower prices than those available after public trading begins, but they also take on greater risk because the project is still under development.

What Is a Crypto Presale?

A crypto presale is an early token sale held before a cryptocurrency becomes publicly tradable. It may take place after seed or private funding rounds but before a wider public sale, Token Generation Event, or exchange listing. In many cases, a presale takes place before the project has launched a product, minimum viable product (MVP), or beta. Instead, investors evaluate the project's whitepaper, roadmap, tokenomics, and development team before deciding whether to participate.

Projects use presales to raise capital for product development, marketing, legal expenses, and exchange listings. Many projects also use the presale to build an early community before launching their token publicly.

Investors usually receive their allocations at or after the project’s TGE, which may take place months or even years after the presale begins. Some projects release all purchased tokens at once, while others apply vesting schedules that distribute them gradually over time.

Pros:

  • Opportunity to buy tokens before public trading begins.
  • Token prices are often lower than in later funding rounds.
  • Early supporters may receive bonus allocations or other community incentives.

Cons:

  • The presale contract may allow the team to change the price, duration, hard cap, or claim terms.
  • Projects are often still in the idea or early development stage.
  • Tokens are usually locked until the TGE and may remain subject to vesting.
  • There is no guarantee the project will launch successfully or secure exchange listings.

What Is an ICO?

An Initial Coin Offering (ICO) is a fundraising event in which a blockchain project sells its newly created tokens directly to investors before they are listed on a cryptocurrency exchange. It is usually managed by the project, with investors purchasing tokens through the project's website or token sale platform rather than through a third-party exchange.

ICOs became the dominant fundraising model during the 2017 crypto bull market, helping projects such as Ethereum, EOS, and NEO raise capital from retail investors around the world. However, the market also attracted fraudulent projects and failed launches, leading to increased regulatory scrutiny and the rise of alternative fundraising methods such as IDOs and IEOs. Today, ICOs are less common but are still used by some blockchain startups.

While presales typically take place during the earliest stages of development, ICOs are often held when a project is more mature, closer to launch, or has already launched a product, and is ready to offer tokens to a broader group of public investors.

Pros:

  • Open to a broad range of retail investors.
  • Projects can raise capital without relying on a centralized exchange.
  • Investors can buy tokens before public exchange listings.

Cons:

  • Limited investor protections compared with IEOs.
  • Projects are responsible for handling security, compliance, and token distribution.
  • Higher risk of scams and failed projects than exchange-hosted offerings.

What Is an Initial DEX Offering (IDO)?

An Initial DEX Offering (IDO) is a fundraising method in which a blockchain project sells tokens through an on-chain launchpad or decentralized platform, usually before or alongside trading on a decentralized exchange (DEX). Unlike an ICO, where the project sells tokens directly to investors, or an IEO, where a centralized exchange manages the sale, an IDO uses smart contracts and an on-chain platform to manage participation and token allocations.

IDOs emerged as an alternative to ICOs after the 2017 crypto boom, offering a more decentralized and transparent way to launch new tokens. Instead of relying on a single company to manage the fundraising process, smart contracts automate token sales, distributions, and liquidity on the blockchain.

IDOs are generally designed to be followed by DEX trading at or shortly after the TGE, although the timing and liquidity arrangements vary. When DEX trading opens, investors may be able to trade their unlocked tokens without waiting for a centralized exchange listing.

Pros:

  • Decentralized fundraising without relying on a centralized exchange.
  • Smart contracts can manage purchases, allocation limits, token claims, and, in some cases, initial liquidity.
  • Tokens often become tradable shortly after the TGE.
  • Investors connect self-custodial wallets rather than depositing funds into a centralized exchange account.

Cons:

  • Demand often exceeds supply, making allocations difficult to obtain.
  • Smart contract exploits or coding errors can pose security risks.
  • Token prices can be highly volatile immediately after launch.
  • Many IDOs still require allowlists, staking, or KYC through launchpads.
  • Thin or removable DEX liquidity.

What Is an Initial Exchange Offering (IEO)?

An Initial Exchange Offering (IEO) is a fundraising method in which a blockchain project sells its tokens through a centralized cryptocurrency exchange rather than directly to investors. Instead of managing the token sale itself, the project partners with an exchange, which oversees the fundraising process, verifies investor eligibility, distributes tokens, and usually lists the token for trading after the sale concludes.

IEOs emerged after the 2017–2018 ICO boom as a more structured fundraising model. The exchange usually applies its own review and listing process before hosting a token sale, although the scope and quality of that review vary between platforms. While an exchange's review does not guarantee a project's success, it provides an additional layer of screening that is generally absent from traditional ICOs.

Unlike an IDO, which takes place on a decentralized exchange using smart contracts, an IEO is conducted entirely through the exchange's platform. Investors usually need a verified exchange account and must meet the platform's eligibility requirements before they can purchase tokens.

Pros:

  • Exchange review provides an additional layer of screening and may reduce some investment risks.
  • Tokens are typically listed for trading soon after the fundraising event.
  • Investors can participate through a familiar exchange interface.
  • Exchanges manage token distribution and investor verification.

Cons:

  • Investors usually required to complete KYC verification.
  • An exchange can suspend withdrawals, delay trading, or change eligibility.
  • Some IEOs are restricted to users in eligible jurisdictions.
  • A listing can still have shallow liquidity or concentrated ownership.
  • Investors depend on the exchange for account access, custody, distribution, and withdrawals.

What Is a Fair Launch?

A fair launch is a token launch and distribution model intended to avoid preferential access for private investors or insiders before public participation begins. In its strictest form, there is no presale, premine, or discounted private allocation, and participants acquire tokens through the same publicly announced mechanism.

Rather than raising capital through early token sales, fair launches may distribute tokens through open mining, liquidity mining, public claims or mints, auctions, or an openly accessible liquidity pool. Bitcoin is widely regarded as the first and best-known example of a fair launch because no coins were pre-mined or allocated to insiders before the network became publicly available.

While the term "fair launch" suggests equal access, it does not guarantee that a project is legitimate or risk-free. Some projects use the label as a marketing term despite retaining hidden developer wallets, privileged allocations, or other advantages. Investors should always verify a project's token distribution and on-chain allocations rather than relying on the "fair launch" label alone.

Pros:

  • Equal access with no discounted insider or venture capital allocations.
  • On-chain distribution may make initial allocations easier to inspect.
  • Reduces concerns about early investors selling large allocations after launch.
  • Can encourage broader community participation and decentralization.

Cons:

  • Projects do not raise capital through early token sales.
  • The term "fair launch" is sometimes used inaccurately for marketing purposes.
  • Equal access does not prevent bots, whales, or early participants from accumulating large positions after launch.
  • A fair launch does not guarantee the quality or long-term success of a project.

Which Type of Crypto Token Sale Should You Choose?

There is no single fundraising method that is best for every investor. Each offers different opportunities and risks, and the right choice depends on your investment goals, risk tolerance, and the level of research you're willing to conduct.

If you're looking to support projects at the earliest stage, crypto presales provide exposure before public trading, but their apparent discount should be assessed against the token’s total supply, fully diluted valuation (FDV), vesting schedule, and expected circulating supply at launch. ICOs can provide access to public token sales before exchange listings, although investors should carefully evaluate the project's credibility and tokenomics.

For those who prefer a more structured fundraising process, IDOs and IEOs introduce different forms of infrastructure and screening. IDOs use on-chain contracts and launchpads, while IEOs rely on a centralized exchange to administer the sale. Neither approach guarantees a successful investment, but both have become popular alternatives to traditional ICOs.

Fair launches may be more suitable for investors who want to avoid the vesting and selling pressure created by discounted sale rounds. However, investors should still examine the initial token holders, developer wallets, supply controls, liquidity, and launch mechanism. A project can provide equal public access while bots, whales, or insiders still gain an early advantage.
