Apart from forkdelta, another great market for ERC20 tokens is IDEX. It is more user-friendly than forkdelta and has rarely any issues with transactions.
But on IDEX you can only trade 'listed' tokens, right? Or is it possible to trade a token where you only know the contract address and the token symbol, like at Etherdelta/Forkdelt? Because that's exactly the reason why I like Forkdelta that much. Sometimes you can make a real bargain when some bounty hunters wanna dump their tokens before the first exchange listing.
I think that this resource has come times more difficult for the previous ones, because there are such exchanges as Tokpie, where a bounty hunter is offered to sell tokens at the stage of steaks. Nevertheless, a bit of a stir is already created on bitcointalk And a lot of talk about how profitable it is to sell steaks or tokens even after the companys ico is completed.
