Most exchanges in the crypto market have always remained popular. However, no matter how good the service offered by some is, they cannot reach the desired user base and go bankrupt. I think it is the same in the DC-Ex exchange and wants to cover its losses by selling domains.
I used it a lot when the stock market opened. Because the user interface and operations can be managed very easily. Web design is very colorful. Thanks to the graphics of the crypto money on it, we can follow the prices.
It also contained many cryptocurrencies. However, some cannot be processed. Since the price currencies it supports are not very popular currencies, I think some of the users have left the exchange.
Although it was an exchange that could not survive, it received very reasonable transaction fees compared to other exchanges. The deposit fee was not deducted.
In short, I can say that I am very sorry that the stock market left the market so early. I think it would be great and the most used exchange if it was serving now.
