You have two choices :
1: sell for Ardors
2: buy n hold until Ignis hype.
or you can buy other assets running on top of nxt then hold for dividends.
I have a lot of nxt tied up in assets on the nxt assetexchange.
Does anyone know if the assets on the nxt assetexchange will migrate to ARDR/Ignis?
Is this even possible? I think it would be great if assets would migrate and would be directly tradeable against BTC.
Depends on the issuer of the Asset. If he wants to have it on Nxt it stays there, if he wants it on Ardor it will be issued there. The person can also think of changing it to a Child Chain on Ardor.
What about assets being able to be traded against BTC on ARDR main/childchains. Is this possible? The big problem is that there is no liquidity in nxt. ARDR should not repeat that mistake.
Marketcap of Ardor raised around 3 more millions USD in three days. Dont worry about that.
