If anyone is considering joining this ICO, it currently appears to be 30% cheaper to purchase with ETH instead of BTC.
It's also about 30% cheaper to buy on ED. I guess some weak hands decided to sell.
The ICO isn't even over yet and I haven't seen any announcement that Ether Delta listed FENX. At work so I can't check for sure. Are you thinking of a different coin?
No just type in the token address on ED and you'll see the listings. Put #0x017188526374f723ec66509ea0c44dd797a33c84-ETH after Etherdelta.com. Every ERC token is on ED by design.
