I was using Dex exchange when Idex launched but then after they started limiting minimum trade for takers and Sellers . It is not good as etherdelta as it used to be in past . I dint find similar decentrelized exchange . Even forkdelta also not upto mark . Switcheo is good where we can trade multiple smart contraccts Ethereum , Neo and others . I like that . I used for some time.
I think IDEX still looks good and crowded. although some updates in the past have created controversies such as account creation and KYC. because we have always believed that ED and FK do not need such a system.
that problem has already solved and only the dex that is based on the US that implements the KYC verification. Idex is still even giving a daily limit for the new account that is not yet doing verification too.
