What are ICO, IEO, IDO, and TGE?

ICO (Initial Coin Offering) , IEO (Initial Exchange Offering) , IDO (Initial DEX Offering) and TGE (Token Generation Event) are common financing methods in the blockchain and cryptocurrency space. The core goal of these methods is to allow blockchain projects to raise funds by publishing tokens, while providing investors with the opportunity to participate. Although they have similarities, there are significant differences in operating mechanisms and processes.

ICO (initial coin publishing)

ICOs are one of the earliest financing methods in the cryptocurrency space, similar to IPOs (initial public offerings) in traditional finance. In ICOs, project parties sell tokens directly to investors to raise funds to support project development. Investors usually buy tokens by paying for mainstream cryptocurrencies such as bitcoin or other supported cryptocurrencies. ICOs peaked in 2017, but due to insufficient early regulation, some projects have been fraudulent, and their legality and transparency have been questioned for a time.

IEO (first exchange published)

IEO is a further evolution of ICO, with token publishing led by centralized exchanges. The project party cooperates with the exchange to sell tokens to investors through the exchange's platform. Some exchanges will audit the project and provide technical support to assist in token publishing. This model provides some protection for investors, but its results still depend on the exchange's audit standards , which cannot completely eliminate risks. At the same time, the project party may also face higher listing fees.

IDO (First Decentralized Exchange)

IDO is a token publishing model that runs through centralized exchanges (DEXs), allowing users to directly participate and buy tokens through smart contracts. Compared with IEOs, IDOs do not rely on centralized institutions, operate more flexibly, and have lower publishing costs. However, due to the incomplete regulatory framework, IDO projects may face challenges such as volatile token prices and uneven project quality. Some regions are trying to introduce regulatory frameworks for decentralized finance (DeFi) and DEXs, which will help the future development of the industry.

TGE (Token Generation Event)

TGE is more focused on the token generation and distribution process than just the financing itself. It usually includes an ICO, IEO or IDO, marking the official launch of the project token. The concept of TGE is more neutral and is used to describe the overall process of token publishing rather than a specific financing method.

Summary

ICO, IEO, IDO, and TGE are the evolving financing models in the blockchain space, each with its own advantages and limitations. ICO and IEO are more suitable for centralized models, while IDO is closer to the decentralized design concept. Investors should carefully evaluate project quality and risk when participating in these projects, and exercise caution.
