I quite like this idea personally. The idea of the index fund in my mind is to provide collateral for the XIO token based on the future success of our projects.
Yes, I think we should put some FLASH into the Index fund. I just wonder how this would be possible since the audit is already underway and modifying the FPY match to send some FLASH to the index fund would not be possible now.
A possible option here is to mint a larger amount of tokens initially when FLASH v2 launches and send these to the index fund. The total supply of FLASH V1 currently around 19 million - we could mint an additional 10-30% and send these to the fund - so somewhere between 1.9 million and 5.7 million.
An important consideration here is although these numbers may seem high, the total supply will continue to increase over time (I believe) and since there is no FPY match, it might be a good idea to increase the initial deposit into the fund.
