What does it mean exactly that it's listed there?
That it is making its way to the market.
That the twins have bought something like one hundred thousand bitcoins - at what price, we don't know - and are about to cash out some of them.
Still kind of confused as to what this means for the market exactly.
It doesn't mean anything as it's not actually approved yet. But when it does get approved, it means institutional investors and firms will have an easy way to throw funds at BTC without actually holding BTC. (Not sure why they'd want that, but hey.)
Of course as more shares are bought, Winklevii will have to purchase additional BTC to be represented, and of course as shares are sold they'd liquidate. Not sure *exactly* how it works, but I think that's the general gist. In the end, purchases of this ETF will (not-quite-directly) contribute to increased demand, and also the opposite.
EDIT: I'm not sure what the above poster meant by "about to cash out." Filing or approval in no way means Winklevii will be selling any or all of 100k coins at market the instant they are approved. They have to own the coins that the shares represent. They don't get to just sell them when ETF is approved, that makes no sense and then they wouldn't have an ETF. They hold the coins as specified in the filling. As more investors pile in they'd have to purchase more coins. Or the opposite. You get the picture.
