Good point on the oracle.  Currently, it's a centralized oracle with an Augur-like fallback system (where users can challenge each other).  Top priority for me is to add something like Chainlink into the system and ensure the data feed is good for years.  There's also a global settlement mechanism where if say, the S&P 500 dissolves in the future, the vSPY tokens just settle at the last known good value.

If the oracle problem were solved, would you buy?  What are top token's you've bought in the past & main reasons?  I'm trying to collect some opinions to help me develop the next stage of this.
