You replied to a question that qidafei didn't ask. He asked if he can use eXch for exchanges until 1 May. He can. The swap service still works and will remain operational for the next 10 or so days until something unforeseen happens or the management changes their mind. He will not be able to swap coins after 1 May and until the new management takes over.

Once that happens, eXch's current history and track record come to a stop. The new team will have to build their trust again from zero. At least, that's how I see it. It will be important to go through the new T&Cs and eventually a new Privacy Policy in detail.
