From my experience so far, I must say that projects that comes up like Ignis are rare that is to say that Ignis is a very unique project. Also, just as I got to know, I will love to let you know that Ignis does not exist as a Blockchain technology on its own but functions hand in hand with the Ardor technology.
Since I was only interested in trading and making profits, I only focused on its own native cryptocurrency token IGNIS. Actually I have not traded on this token, IGNIS, recently but from my last experience with trading it, it is a very nice one and I can tell that I really made a lot of profits from trading it.
Moreover, in case you find interest in this token, IGNIS, you should try signing up for an account with TOKOK, HitBTC, Probit Global, Bittrex, Indoda, Stex or Bilary because these are the exchanges I can assure you that you would be able to trade IGNIS on but as preferred by me, personally, I traded IGNIS on HitBTC but you can try out other listed exchanges that supports IGNIS.
Further more, just as I mentioned earlier, Ignis does not exist separately but functions with Ardor technology as a child chain and Ardor as that parent chain and they function this way to ensure maximum efficiency is reached, but since I was only interested in trading its cryptocurrency token, IGNIS, I paid only a very small attention to how it functions. Also, I got to discover that Ignis functions with Ardor using the proof of stake algorithm which I think is more preferred.
Another interesting part of Ignis is that, it is very active on social media and gives active updates to its users and also has a very responsive support. Personally, I do get updates from Twitter, telegram, Reddit and even on discord, and from what I know, I think there is also a relationship between Ignis and Nxt but I have not been cleared on that fully yet.
In conclusion, you just have to put in mind that Ignis functions side by side with Ardor which is the main Blockchain platform, however, I can't fully assure you that you going into Ignis will be a success but try and make your own research on this project, Ignis.
