Trading on NOVA exchanged has stopped at beginning of this week.

Now there are several exchanges we are in contact with for adding Parallelcoin / DUO.
But nearly all exchanges are asking a listing fee, so it might takes some more time until Parallelcoin will be a added to a new exchange.

If there is an exchange willing to add Parallelcoin/DUO FOC, it would be much appreciated, please contact us.

Also check out the latest developments of the new wallet, which might help in your decision to list DUO FOC:
