Decentralized market look like a good chance to make profit, etherdelta is one of most popular but look like all token on this market are full of speculation...... What you think about? Solid project like Centra are good investement for medium time or is too risky?
I think ethdelta is a good exchanger site, because it's decentralized and only your private key is needed in order to have a full control of your account.
I may say its good trading here, because most coins/ tokens specially erc20 tokens are listed here and can use on different transactions.
