Hello, you're not quite right in your interpretation.
The Ardor tokens, ARDR asset id 12422608354438203866 in the Nxt blockchain until the snapshot, "power" the main chain (there's only one main chain) in the new platform. This means they are used to generate blocks and secure the whole Ardor ecosystem. But they are exclusively used for this purpose.
IGNIS is the token for the first child chain under Ardor. Child chains in Ardor, unlike the main chain, can have for starters all the existing features in the Nxt blockchain. Issuing assets, sending messages, voting, trading digital goods, etcetera. So IGNIS has all the features, except for generating blocks, which only ARDR can do. But other than this, IGNIS does not "power" anything. Any other child chain that will be added to Ardor, including other few initial child chains like Janus or Bitswift, can have access to the same Nxt features and other features that will be added to Ardor.
What is particular for IGNIS is that it is the first child chain, hard-coded by developers, so it becomes the initial transactional token for many things inside of the ecosystem, which should give it good usage and volume.
And about investment advice, it is difficult to give. ARDR has in principle more long term potential because it will gather fees from all child chains, but IGNIS will have more usability out of the box. You should make your own investment decisions after reading and understanding the platform.
Hi VanBreuk
thanks for taking the time and answering my question. For the most part, this is in line with what I thought about Ardor. But I understand that the terms and language ("power") to describe it are not very precise.
Nevertheless, you are right. I need to read up on it. I had had a glance at the whitepaper some time ago, but a glance is not enough to understand it.
What I have seen though is that the community is quite large and active, and that the outside representation of the platform is very professional. This is promising.
But yeah, need some time to read through all the stuff.
Thanks again for your time,
Trinketmage
