Is this text in the T&C new? I guess it's just to cover themselves in the event of something going wrong, but it does sound kind of arbitrary.
BETA Notice
Novaexchange is currently in BETA mode in production mode until further notice. The BETA tag will be removed once all known bugs are fixed and no new bugs encountered for a period of 3 weeks. While BETA tag applies things can go wrong and Novaexchange will in timely matter help the user to restore (if any) digital currencies. A trade that has gone wrong can be reversed during 48 hours of the timestamp of the trade and only as long as the currency remain on Novaexchange, once withdrawn or 48 hours has passed that transaction cannot be reversed.
So all trades are final........ unless the counterparty still has funds in their account.
