How will I know if my private keys are not stolen. I just login yesterday to sell a coin. Are there any reports of stolen tokens from Etherdelta users? This is so scary. They are hacking the dns of cloudflare to manipulate etherdelta.
It won't be the either way. Etherdelta never has access to the private keys of its users' wallets (except in the case if you haven't import keys to phising page as shown by hackers yesterday). It works in completely decentralized way which enables users to have complete privacy and freedom in operation. As a result, none user will find tokens stealing from their wallet.
However, where actual risk lies is in trading tokens on Orderbook as ED confirmed on Twitter that Orderbook has been compromised and there are fake orders on it. So it is better to wait for ED official announcement about recovery before commencing trading.
