You can start voting for the currencies to be available for trade now: https://rawx.io/poll.htmlIf you are missing a currency just tell me!
The exact release date for the beta will be announced soon!
Blackcoin (BLK) and Decred (DCR) should added.
I would also like to suggest (CBX) CryptoBullion as it would be nice to see it distributed on a few more exchanges.
