Bitcoin is not going to disappear, but I think there's a real chance of revisiting $6000 this week and next month. I think the biggest holders like the Winklevoss twins are going to sit it through, but the investors are going to cash out to avoid the risk exposure and the traders are going to short Bitcoin.
It will be like the SEC/CFTC hearing earlier this month, except maybe worse because the event on Monday also involves European banks who see their profit threatened by cryptocurrencies.
