When a cryptocurrency startup firm wants to raise money through an Initial Coin Offering (ICO), it usually creates a plan on a whitepaper which states what the project is about, what need(s) the project will fulfill upon completion, how much money is needed to undertake the venture, how much of the virtual tokens the pioneers of the project will keep for themselves, what type of money is accepted, and how long the ICO campaign will run for. During the ICO campaign, enthusiasts and supporters of the firm’s initiative buy some of the distributed cryptocoins with fiat or virtual currency. These coins are referred to as tokens and are similar to shares of a company sold to investors in an Initial Public Offering (IPO) transaction.
