So SecondMarket hasn't bought shit for over 3 months now.
Looks like it. Should probably worry those who believe that the listing of an ETF automatically means new price surge.
You may be right with that. But couldn't a real ETF be another investment vehicle serious investors want to use in order to get their Bitcoin? What are the advantages over SecondMarket in this case? (compared to e.g. the Winklevoss' COIN)
The advantage of an ETF is that it is accessible not only to high-net worth individuals, at your regular broker. I think it'll help a lot, but it will depend a lot on the circumstances of when it is launched because the sentiment/price environment will dictate demand.
