As I have observed, Etherdelta is the most updated exchange when it comes to new ICO, or the new tokens from the ICO. Can you tell me more exchange that are like this?
It's easy to get listed at etherdelta because almost all ico nowdays are erc20 token which is the type of token that is traded on etherdelta. It's good now after the ethereum fork but before that it's hard to use etherdelta because of the lag.
Yes, most coins in etherdelta are ERC20 that ICOs are using right now so after the end of their ICOs it will be available in etherdelta right away.
