I've been contacting countless exchanges. Most of them don't even reply, some of them want >4 BTC for listing. This is the current situation with exchanges.
Still we are in novaexchange and they should open deposits soon, but I can't tell for sure as it's up to them.
Meanwhile, I'm searching for new exchanges every day, but at the same time I don't want to get listed on a shady one, as I don't want people to risk loosing their money.
About development, I understand it may look like we just "dump version", but again I'm working every day on xcn with my little free time; we can't count on any premine, ico or part of the block reward.
Still, we have made important changes and fixes since I started working on this project 1.5 years ago.
The XCN community is made of honest guys that believe in the technology, not the pump and dump kind of users, and this is also a result of the serious and honest approach to coin development we are used to.
