Yes another high volume capable exchange for Pandacoin would be nice even though Mintpal is good for us, times like this show centralization is a concern. Some have noticed our Pandacoin PND suddenly was missing as a supported coin at CoinPayments.net merchants for instance. From what I have come to understand from working with Coinpayments on previous similar situations is they use Mintpal to monitor Pandacoins volume.  They monitor all their supported coins similarly and any extremely low volume coins automatically get shut down temporarily if the minimum amount of trading is not occurring daily.  I have had to contact them in the past to return Pandacoin service but usually Pandacoin will automatically show back up once Mintpal has some verifiable activity. I am fairly sure that they also monitor the other larger exchanges too, so this blackout of service wouldn't have to occur, if an alternative large exchange was also available in parallel to Mintpal for our Pandacoin.
