IGNIS does not have its own blockchain, so anything done on the IGNIS chain needs to be bundled onto the ARDOR chain.
As the price of IGNIS increases, it will generate a lot more interest than it does at present due to it being a child chain, and not the main chain on ARDOR.
Also, as the price increases, and the price of ARDOR falls, it becomes cheaper to process the transactions on the ARDOR chain (it has been hovering between 2 and 3x the actual cost in IGNIS, so 1 IGNIS fee on the IGNIS chain would cost 2-3 IGNIS on the AROR chain), so once the prices swap round, the inverse would be applicable and the bundlers would be charging a rate of say 0.2-0.4x IGNIS per ARDOR of fees (so a 1 IGNIS fee would be 0.2-0.4 IGNIS on the ARDOR chain), making the transactions more cost effective on a chain which cannot be forged, and driving up the rewards on the ARDOR chain for forgers, generating even more interest in the ARDOR chain in general, which will be good for the benefit of holders of both ARDOR and IGNIS.
