I also used etherdelta & many peoples come to ed for tarding.now ed is one of the most famous crypto exchange in the world.many peoples complain against ed but I don't see any problem in ed.
I hope ed is the best exchange.
The only problem with etherDelta is that the price of some coins is lower than on other exchanges. But today the situation was noticed when in certain regions the resource etherDelta simply refuses to work.
Perfect playground for arbitrageurs. Its actually kind of easy to make money with EtherDelta. Besides of this tactic, people can buy some coins very cheap in there and therefore buy much more then they would have been able to on another exchange. Its good to accumulate tokens there for long term hodling. My last purchase with good discount there: AION.
