eXch may have shut down, but you shouldn't worry! At BitMixList, you can find all of the highest quality private exchangers available on the internet.
With the sad exit of eXch, some exchanges that were pretending not to need KYC are now torturing users asking for the documents, proof of address and proof of source of funds. I personally don't think such services deserve to be among the likes of wizardswap.
Please look into The Changeltd's case and see if it's worth reviewing its listing.
