It's really possible because the market has been really surprising. It could rise up and go down easily and $7k is so near to its current value. We could expect all the best from Bitcoin but we can also expect the worst at the same time.
The market is volatile so this possibility could happen anytime.
I also think so, in general we are seeing an uptrend but besides that the price of bitcoin will decrease at some point. $7000 is still a good price if that happens.
