Absolutely no way ETF goes through.
But you think it will have an effect? Why should it makes btc rate drop? Any correct trader knows the chances are low no?
Stranger things have happened. And that big meeting they had a couple of weeks ago are not the actions of something that's been outright rejected. They want to know more.
I think quite a few people have bought in with the expectation of a further rise if it's approved. Maybe they'll throw in the towel. There'll be a dip. A full on crash is doubtful as ETF fever is only part of the general uptrend that's been going for a long time now.
And there are two more applications to consider in quick succession after the Winklevii one. I doubt they'll have the gloss, but perhaps they'll add some refinements. Overall though I think rejections will be down to Bitcoin itself and no applicant can do anything about that.
