I am wondering if there is a security that tracks the entire crypto currency market as a whole?
There is one similar thing I am aware of, Iconomi. Go check it out. I am not using it right now but it looks like a cool idea.
As I understand it you can go to that site and setup a portfolio, you can choose almost any coins youd like with their relevant percentage. This portfolio will then be advertised on their site, you can then invest ICN tokens into it for which their smart contract will buy the assets in their relevant ratios to back that up. Through this you can probably do an ETF type of thing.
**Disclaimer**
I am not a master of this, I didnt spend a hundred hours researching it, but the above is basically as I understand it. It is something worth looking into in my opinion.
I havent scam checked them or anything, so take my above suggestion with caution and check them out yourself properly.
