Datacoin was approved to be listed on HitBTC, it was frightfully expensive so we didn't proceed
We are on a maby list at Kraken
There is currently an application in with Bit-Z
Recently I have sent out applications to a few Japanese/Korean exchanges, not expecting a reply back for awhile
considering how busy they are with influx of new users.

Active development will get Datacoin on the exchanges, sure you can buy your way in but it's only a matter of time before
your coin is on that delisting/low volume notice.
