We just added NxT to AltCoins Market. There you will find live statistics and a currency converter to calculate your NxT to other altcoins. You will be able to setup an alarm to email you if the price reaches a level and of course we have live charts as well (area chart for unregistered members and candlestick for members).
We hope you like it! If you have any suggestion you can contact us on Twitter.
