Another tool (in beta) for better managing money on your own, Prism lets you setup an index on your own. From the post How Blockchains Will Disrupt Mutual Funds…You Build Your Own at Never Stop Marketing:
Prism is the world’s first trustless platform for creating portfolios of assets.
Designed and built by ShapeShift, Prism uses smart contracts deployed on the Ethereum network to bring custom portfolio management to everyone.
You can create and rebalance your own portfolio, as well as browse the public portfolios of others and follow them.
So that is exactly what I did.
Now, my one issue with the site (at the moment) is the relative limited number of coins that it supports. I had hoped to create a broader index of coins, but there are only about 25 or so coins (if you have ever used ShapeShift, you will see the exact same coins).
