An ICO is a fundraising mechanism in which new projects sell their underlying crypto tokens in exchange for crypto. It’s somewhat similar to an Initial Public Offering (IPO) in which investors purchase shares of a company.
ICOs serve as a way to raise capital from the public by distributing a portion of the crypto assets to early investors. They have been particularly popular in the blockchain and cryptocurrency sectors. However, ICOs have faced scrutiny and regulatory oversight due to risks including fraud and market manipulation.
