In the same way, where traditional startups receive business funding before launch, projects that deliver the first DEX donations receive funding from individual investors. Unlike the initial public offering, investors in the first dex offering have never had a balance in the project. ‍ IDOs have certain advantages that can make them more attractive than ICOs and IEOs: faster money-making, faster trading, and lower list costs. ‍ The first offer of DEX or IDO refers to the introduction of digital currency in the devotional exchange (DEX). At IDO, the blockchain project makes the first public money in DEX to raise money for trading investors. IDOs are similar to initial exchange offerings (IEOs), where crypto projects present their tokens and raise funds through intermediate exchanges because both allow for faster trading than earning money. However, medium trade imposes stricter land rules including: ‍ Payment of a large sum or donation of part of the tokens in exchange; Preventing a project from registering their tokens on a competitive exchange; Having a very limited approach to regulating the parameters of the token sale of a project. IDOs, on the other hand, can provide less expensive token sales with the list model. First, IDO provides immediate investment without slipping through the available DEX pools. By comparison, it has the cheapest listing costs. And like IEOs, it allows for faster trading.
