We have not raised any money for duelcoin and have been giving it away for free, so it is essentially valueless and is not listed on any exchange.  You could still buy / sell this coin by communicating with other users, as was done in the early days of BTC before exchanges.

We are soon launching value backed currencies which will be listed on exchanges.

We do want to reward early adopters and therefore your duelcoins may convert to valuable coins once we launch those currencies.
