If the coin has several exchanges, of course, the coin user chooses an exchange that is easier to use, so there is a part of the exchange whose volume does not exist. This makes the exchange remove the coin from the exchange list. For example CVC. CVC coins registered around 29 exchanges. And the lowest volume is Radar. Yes, in my opinion, there are fewer Radar and CredoEx exchanges that trade CVC coins. And there is a possibility that the coin will be removed from the CredoEx exchange.
Beside of that, not only project and investor who aim for earn money. But we must think that crypto exchange need fee from user's activity like volume trading and withdrawal fees. And then maybe if slot is free, can be change to another coin that want to listed in there.
