You may or may not have heard about Balancer, a tool to create custom cryptocurrency-based Index Funds (being non-judgemental, I choose randomly from page 22 on Coingecko.com: OmbreCoin, DignityCoin and RawCoin: by adding $100 worth of each to the fund, Balancer will adjust the exposure to each according to price movements - DignityCoin goes up over a certain period of time? Balancer will sell some $DIGNITY to buy more $OMBRE and $RAW)
It would be very interesting to have a Balancer-like implementation available on Morpher, enabling users to create their own stock- or commodity-based pools: a pool representing S&P500, MSCI World, Bitcoin and Sugar? Could be done.
