NXT, ARDR, JLRDA and IGNIS are all from the same developer, Jelruda. They announced the IGNIS IPO recently, where you can trade NXT for IGNIS on their platform. They also announced the Ardor platform, which is supposed to act as NXT 2.0 and that they would cease working on the original NXT platform. The IGNIS IPO was essentially to reward NXT adopters. Anyone who holds NXT in their NXT wallets later in October (date not set), are given free ARDR. NXT will then be merged with ARDR. What does this mean? NXT is virtually worthless by the end of the year. NXT is one of the few USDT pairs on Poloniex and can be shorted from here quite successfully.
