I was hoping it wouldn't go below 10.000$ but now it did.. IMO the 10.000$ was a barrier which is now broken, making it possible to drop to 5000 - 6000$. But hey, it can be an opportunity.
Yes, drop below 9k would be dangerous for btc price and it can further drop to 6-7k.
If it can back to 10k then it should be ok.
