Alcor Exchange gives you the ability to open a new market for 2 existing coins that do not currently have a market pairing.

To do this, first go to the "Markets" tab and look for the button that says "Open new market"

"Why would I open a new market?"

• If you wanted to exchange any of your tokens for another one that there currently wasnt an exchange for.

• If you were developing your own crypto currency and wanted to give others the ability to purchase it using their existing other coins.
