I also feel worried about what's happening around EtherDelta. I also noticed that my coins on blockfolio are not updating prices but we don't have any choice but to use it to trade our erc20 base tokens for ethereum.
What about
https://idex.market ?
idex is fine, but if you want the same as etherdelta, you can use
https://forkdelta.github.io/is a frontend fork community driven, it is the same contract and orderbook so you can find your erc20 tokens there.
remember to use metamask or an hardware wallet, better be safe than sorry.
