There are some phishing sites, they imitate etherdelta, but they have subtle differences, maybe etherdelta2.com, or etherdelte.com, so when you have to open your eyes.
EtherDelta isn't safe this year due to many attacks on their servers and even on their DNS that you'll then redirected on their clone phishing website in order to get your keys.
Phishing is one of their main attack because blockchain servers are 99% attack proof so their only way to get money is to attack crypto holders remotely.
