Let the SEC just cut the nonsense and reject every open proposal and no longer allow new ones to come in, but that's just wishful thinking.
While this might be nice to have in terms of the attitude that governmental approvals have never been expected to happen and that bitcoin does not need any 'official' approvals, it probably would harm the market a lot.
Unfortunately the majority of people invested into bitcoin are only looking to make fast gains.
They support each proposal which could bring new investors (or better: their money) into the market. And they sell the very first moment some news against new money flowing in are published.
In my opinion bitcoin doesn't need any approvals at all. Bitcoin shouldn't be used as a mean of high speculative investments at all.
I'd favor bitcoin being used as a currency and means of payment. Rising in dollar-value through adoption and technological performance, not because of rich people playing a game to get even more rich. But unfortunately this is not the case.
