The user interface for open dax is very simple and easy to use. I have no issues with using it. It's a great platform for all kinds of trading activities. It has been a great experience so far. I highly recommend this product. Nothing in particular. I am using it as my main trading platform and it does what it says on the tin. There are many different cryptocurrency exchanges out there but none that can provide the level of security that this one provides. I have used other exchanges before but they lack the features and security that this one offers. This is by far the best option out there when it comes to crypto trading. The best part about this software is that you don't need to worry about having to download any kind of files or install anything. You just sign up and start using it.
