An ICO project issues a token to raise capital, so the question is is the number of tokens limited? When and how to distribute tokens?
In my own opinion, it is really important to the projects to have the number of tokens or it must be limited so that , the investors and traders can determine whether that coins/tokens is suitable for the price issued by the ICO management. Usually, the distribution of tokens may occur once the ICO is over or concluded, so that the management team can secure the safety of investors.
