What are these – ICO, IEO, IDO, and STO

Here are the popular Presale types

This is the first type of Presale to appear in the Crypto Market. It refers to the method of raising funds for a Crypto Project that seeks to enter the Crypto Market for the first time by selling some of the cryptos at a massively discounted price.

ICO is very similar to Initial Public Offering (IPO), which is used by companies to raise money from stock exchanges.
