I personally wouldn't recommend anyone use etherdelta if you using it for big amount of money use at your own risk, the site is extremely unstable, orders get stuck , sells gets stuck, buy orders get stuck and just vanish without a trace.... Nothing seem to ever work correctly. Owner of site has not fixed any of those issues. The platform is a traders nightmare...
I've had problems logging in at times, and it certainly isn't the most user-friendly trading site... but sometimes it is necessary to use it to trade in the more obscure coins that aren't listed elsewhere. I don't think it's too bad, just not as easy to use as bittrex etc.
