I certainly won't be too bothered if they don't, in fact I hope they don't. Bitcoin is doing fine without those corrupt multi-lettered US bodies anyway. It always has & always will. It's designed that way.
In the same way I won't be bothered if it doesn't come through, but it adds value to Bitcoin's utility, which is the most important aspect of these developments. It's just a price tracker in reality without an underlying value, but it helps damping down the 'shady' nature they initially thought Bitcoin had. It's quite the opposite world, but the more 'legitimate' usage Bitcoin enjoys, the more traditional parties will start to grab hold of Bitcoin.
The previous ETF's were rejected mainly due to Bitcoin's unregulated nature, which currently has changed significantly, but I'm not yet sure if it's enough for them to let an ETF come through. On the other hand, with parties as CME and CBOE having an important bit of influence and a trustworthy track record in their own fields, they might actually become the first entities who successfully get their ETF's approved. It makes a big difference for sure.
Does anyone even know what happened with the 'review' the SEC granted to the Winklevoss ETF? We're more than a year further and we still haven't heard anything from them.
