.I donot understand what can i do?why hacker are attack general people ?prayer for meSorry to hear that. Hackers are always attacking traders and exchanges because of all the money involved. Using Etherdelta's front-end interface to input private keys is fundamentally insecure. You should use MetaMask and use a separate, smaller trading wallet for short term trading if you are going to use Etherdelta. Their DNS was compromised recently, so you likely got phished by the fake site.
