It would be better if they launch the campaign later when the platform goes live.

If they do publicity now, they cannot use the platform now. They would eventually forget about it, till the platform of funds is launched.  Iconomi team or the investors wouldn't benefit in this way. The only effect would be the increase in ICN/Btc rate.

So the better approach, I think, would be to attract investors for index and performance funds when it will be live.
In this way, we(existing investors) will also benefit. As we would earn from the fees on their investments.

Price of ICN doesn't actually matter, thing that matters is how LARGE the dividends are.
