Waves Platform (New Beta Client) is a relatively new player in Crypto that is on the up. They definitely have problems as does any DEX due to having to work with gateways, but design and user experience is at the forefront leading to better adoption.
I think they will iron out the problems and become the best DEX which is not controlled by countries. They do actually sit somewhere between DEX and EX being a business and not community controlled but sometimes that is a good thing.
