Yes they are both the same and we can easily tell it because their sites names are verry simillar to each other. And i dont think etherdelta is dead because id still access it and i still traded my tokens thru it on the past days . I dont also tried to use forkdelta but if there were problems in etherdelta , i may then try to use forkdelta as an alternative so that i can still trade my coins .
I suggest youd better try etherdelta because this exchange is also good when it comes to trading or buying alts and tokens due to the fact that it is decentralize which means all transactions are automatic without human supervision for a better and faster processing.
Ed is also known to be the first trading platform that accepts ico coins to be listed on their exchange as when compared to other.
