how to go from collection to exchange

Hello, due to lack of knowledge, I made the mistake of adding more than 700 coins to my personal collection and they were actually for exchange.  My question is if there is any way that I can make all the coins in my collection available for exchange at once or do I have to make the exchange coin by coin.

Hola, Javier. Que yo sepa no hay forma en que uno mismo pueda hacerlo por la web. Si sabes programar, sí mediante la API. Pero lo más fácil es que se lo pidas a los administradores. Tal vez puedan, y si no, te dirigirán a Xavier.
