Could you kindly tell us your official phone numbers and registered address, wherever it is that you operate from? Surely, as a non-anonymous exchange, you wouldn't be operating anonymously, would you? I would like to know who I am sending my personal identification to, and I am sure the op feels the same way too. You must admit that nobody in their right mind would send their data to an anonymous company.
For example, these are the two exchanges I use, and I wouldn't hesitate to send them my ID's. This, because I know that if anything goes wrong, my lawyers can find them. I cannot find any information for Changenow outside their support ticket and telegram.
