Livecoin: https://www.livecoin.net/ - still in maintenance but recently began allowing deposits but no withdrawals
Binance * pending but no assurance of listing
Poloniex * pending but no assurance of listing
* Spectrecoin have submitted a full application for a listing on Binance and Poloniex.
The team has had long time standing applications on the above as well as other popular exchanges but, is not inclined to pay high fees for a listing which is harmful to the project. Trading is active however on the above exchanges with Amsterdex and Crex24 being safe and secure exchanges to trade.
As many learned from the recent Cryptopia hack....never keep more coins on any exchange than you can afford to lose access to temporarily (best case) or lose completely (worst case)
