ICN index will go down along the time with the actual portfolio. Bitcoin and ethereum should represent >51% of the fund . Altcoins in the index should be less. Lets see ico investments on performance fund and wait next year for sharing profit.
You are more than welcome to create your own fund and set the rules according to what you think is best.
ICNX has a different outlook. If you are interesting, read the answer here:
https://www.reddit.com/r/ICONOMI/comments/5df4ow/icnx_question/ICNX is doing what it should be doing. The index represents the blockchain economy. If the blockchain technology is to succeed, we shouldnt look only at bitcoin. The dapps are what will drive (or not) this technology forward. If you want to limit yourself only on bitcoin, then i suggest you only buy bitcoin. Or as Daparski said, create you own fund on the ICONOMI platform (when it launches) with your own rules, and maybe you get a lot of followers - a lot of money for you as the fund manager.
But I hope, the blockchain devs will deliver the dapps with real world use cases for the people. And when the people start using them, sky is the limit. But until them, the whole crypto world is mostly speculation.
