sub $10k IS over.
but the thing is, in bitcoin market because the market itself is small and order books aren't that packed with buy or sell orders, a small manipulation and/or panic can pull the price lower than the strong support (being $10k). but since it is not real downtrend it won't be big or even last long. which is why it is said to be over.
basically at any time, fluctuations within 10% should be expected of bitcoin.
