It appears that someone has tried to front run the release of the upcoming tokens that will be taking place on the NXT platform. Jelruda tokens will not be available until August 5th, but there are tokens with similar symbols listed on the NXT client under the Monetary System (Currencies) tab. These are people who have created their own currencies with similar symbols to try and fool folks into thinking they are buying the genuine article. The fake token symbols are JRLDA, IGNIC, ARDRX, ARDRC.
Buyer beware! Please make sure you are buying the genuine article before purchasing your tokens. If you are keeping up with the release of Ardor and Ignis, then you would not be fooled, but those who don't do their due diligence will be.
NXT is aware of this and has warned people via a post found here https://www.nxter.org/nxt-news-july-2017-iv/#scam_alert
I am pretty impressed with the NXT/ Ardor/Ignis project. They are moving along in their development and seem to have a clear mission on what they want to accomplish. I will be following this very closely. Don't let this nonsense spoil you on this project, its definitely worth checking out. You just need to be aware and pay attention to the real release dates and symbols of the genuine tokens.
