DDex exchange is a popular decentralized crypto currency exchange that isn't that popular amongst newbie traders but very popular to the seasoned/expert crypto traders because of it's complexity that allows them make more profits on the exchange while trading BTC and ETH.
The exchange wasn't designed for traders who aren't well informed and equipped about cryptocurrency trading because the exchange interface might appear confusing/puzzling so I suggest newbies shouldnt trade on the exchange inorder not to get confused. The exchange doesn't accept flat currency transactions so new traders will even find it very hard to access the exchange with flat currency.
The exchange allows experts traders to earn by lending out by their assets to other traders and earn interest on them which brings about the profits they get to enjoy using the virtual exchange and they can also borrow from other traders also. The fees are very competitive ,they charge a flat fee of 0.1% and the most fascinating part of it all is that they don't demand withdrawal fee from traders which sounds really good. At the moment I'm not sure the exchange has a mobile app yet.
