Hey,

First, your ICNs won't be invested in the ICNX, so you won't get any money directly from the INDEX rise.
If you want to, you would have to invest directly in the ICNX.

Second, no way to calculate that for now. Your ICN will bring you money from the fees collected on the funds.
The more money in the funds, the bigger the dividends. What's good with the rise is that it will attract more and more investors, thus bringing fees to the platform, and dividends to you.
