Etherdelta is nice, but it get more exposure to the token and increase it's liquidity some larger exchanges are needed. Atleast in my opinion...
After what happened today, I really do not like Etherdelta and hope Peculium will not be listed there. Unless Etherdelta does some serious changes, which I think they have plans for
You know you can trade there any ERC20 token even if it's not officially listed? There are lots of people doing trades on coins not officially listed there, so you really can't stop it unless you do some black magic on the token contract.
