ETFs may have a chance now that SEC are defining what is a security and not in the cryptocurrency ICO space
ETFs may have a real chance, if the offshore exchanges aren´t responsible for a huge part of
BTC trading volume anymore. With btc-e gone, Bitfinex in trouble (if you believe the rumours about
Tether), things are looking promising for a future Bitcoin ETF.
Besides there is this other ETF, not by the Winklevoss twins, who is taking a different approach and
therefore maybe has a better chance for approval.
