Because ICO is an investment, we spend money, and the money may not be used according to the agreement when the ICO is taken away without clear information or better known as Scam. Some things become the problem of the ICO Scam, which is the unclear project, the purpose of collecting funds made by developers and teams that are unclear or not emblazoned. Usually this will be explained in the whitepaper. Therefore we must be more careful and observant if we want to invest in the ICO.
