ETFs are necessary for cryptocurrency market to get a new injection of capital and make it more dinamic. I think investors also demands new ways for inveting in cryptocurrency.

If a big traditional financial company developes that ETF, the impact will be much direct. But if they do not, others project like ICNQ will do it. It would take much more time for them to build the infrastructure and get confidence, but it would bring big investors to cryptocoins eventually.
