bitcoin stable last few days ,but now sudden high touches, 9100 $ . what will be imagine in next month feb-2020

Hopes are positive until the next May, so it is not surprising that we see such highs.
It's normal to see hikes up to $ 15,000, but that doesn't mean we'll see 100% hikes.
On the other hand, especially in the short term, the price has increased by more than that 20%, so we may see a correction that brings us back to 7100 dollar.
So if you are ready to invest in the long run, this may be a good time.
