My thoughts on the news is that the index fund will continue to pave the way to increase adoption for the asset class. It gets cryptocurrencies much closer to be an investable asset class although only for accredited investors at this point. This will be a great opportunity for volumes to increase as markets in the space still remain inefficient so prices may not always reflect true demand/supply economics. It will also help those bigger investors that are on the sidelines and hesitant given concerns on security and knowledge about the function of digital wallets.

It will also increase the price action when coins are added. I am sure that Coinbase will want to add the most attractive assets available. I think that Dan Larimer's creation are known to be of the highest quality so STEEM, BTS, and EOS will be high on the list of consideration. Although there is some competition given they are not in the Top 20 (except EOS which is still in ICO mode and probably will not be considered until it launches), the fact that these assets solve for speed, transaction fees and scalability will make them attractive.
