Volume is one of the most important things for most new projects along with speculation because at least early on in the project most of investor sentiment is based on speculation of where the projects headed
Yeah. Very important in the business, that's why I think that most exchanges will not list token or a coin that will not have much trading activities or bring in more volume to the exchange.
Initially there was no such concept like ICO and anyone was mining tokens and was adding to exchange, but very few tokens was getting traded at exchange and that's created problem for exchanges.
