Alternativ kannst du es ja einfach austesten, meistens kannst du die Fees selber konfigurieren, sodass es nur ein paar Cent kosten sollte.

An important feature of EtherDelta is that placing an order doesn't involve an Ethereum transaction. Placing an order involves signing a message, which doesn't cost a gas fee. This means that placing an order on EtherDelta is completely free: there's no Ethereum transaction fee and there's no fee if the order trades. The one and only platform fee EtherDelta charges is a 0.3% fee paid by the person executing an order (paid in the instrument being sold).
