How to trade tokens not listed on Etherdelta, but obviously traded there as market price on Coinmarketcap.com referring to Etherdelta.

This is something you just need to learn if you want to be able to pick up projects before they hit major exchanges. For some reason unknown to me, many tokens are not automaticly listen with their ticker on the ED list of tradeable tokens. At Coinmarketcap.com one can see in the markets overwiev that they are listed with the pair (adress/ETH). Like BitDegree in the screenshot here. And like Lamden and more.

To be able to buy or sell BitDegree tokens one must add it manually in the ED plattform. It is really fast if you know what to do:

Click Explorer in CMC.

Here you have everthing you need to add the token manually. Contract adress, Token ticker and decimals.

Then go to Etherdelta, and in the tokens list, go right to the bottom. Click "other".

This should come up. Just fill out the fields from the explorer.

You are good to go! :)
