A contradiction if previously the price of bitcoin experienced a drastic increase from the price of $7000 to $8200 associated with ETF posted by Winklevoss brother's against the SEC, but now when the $500 price reduction after rejection occurs is not associated with the SEC. However, I see like that also when rejection occurs by SEC bitcoin prices are still at $8100, mean that only gives little effect to the bitcoin price reduction.
Agreed that just something else and this reason
You miss the point in this story, nobody even mentioned Winklevoss ETF until the moment when it is rejected by SEC - so that increase in price was not caused by this ETF, but with a completely different one by Cboe BZX Exchange&VanEck SolidX Bitcoin Trust. Someone just used this news and make some FUD which caused a short-term decline in price.
The ETF I mentioned is still under consideration, but as you can see the effect of this news has weakened and price is went down. There are lot of weak hands out there, for them bad news is bad news, even if it is almost insignificant.
