I'm not sure that I'd lead with speculation from the Winklevosses in order to convince a skeptic. Your other three points are much stronger.

Also, only the latter two are actual economic developments, rather than analysis. The upcoming Congressional hearings might be newsworthy too.

lol at a couple of dudes who are publicly known to be existing large amounts in bitcoin stating that it "should be worth a lot more!".

If they did not hold bitcoins, you would fault them saying they did not put their money where their mouth is...

One can never be right against the HN crowd. sigh

Their speculation might not be worth much, but if they succeed in setting up a bitcoin ETF it could definitely boost bitcoin's credibility.

1. The Winklevoss name doesnt exactly boost credibility.

2. What you're describing already exists.
