Cryptocurrency index funds make no sense in general - the correlation between coins is too negative for holding a basket of them to make sense. You want to diversify over uncorrelated assets. Holding offsetting long and short positions makes zero sense, and due how most alt-coins are priced by their ALT/BTC pair, holding most altcoins essentially means shorting everything other than Bitcoin and maybe Ethereum. If you want crypto exposure, just buy BTC and Eth. Due to their volatility, you'll want to have a healthy cash balance and target a constant fraction of that in exposure - essentially, selling half your coins if the price doubles and buying back double when the price halves. Read up on the Kelly Criterion for the full explanation as to why.
