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 most cases, this is the case, there is a certain limit of tokens. However, there were such companies (for example Ripple) so they released only part of their tokens (coins) and then can still release. There are also cases that the tokens are burned, in order to increase the price and the demand for the coin.
