I am not very convinced to see price reaching at that level. There is no solid reason for this to happen. I will say it would be worth to see 1000 $ mark by the end of next year as stable price like it is now at above 550 $. We can not predict happenings as possibilities are endless but should have a fair price range in mind when it comes to talk about it.
There's no solid proof or a firm evidence that's why this is called "speculating".
maybe the price is too great for a short time for the price of bitcoin, although it is not impossible however, it will be very difficult, because when the price of bitcoin reached a price of around $ 1000 - $ 1500, many people who have a lot of bitcoin will start competing to sell bitcoin them. and I predict if the price rose within a short time, then the losses will occur in a short time
The only ones that are going to sell their Bitcoins at that price are the people who aren't into holding Bitcoins for a really long time. Good things come to those who wait, like they said. It might be a good idea to sell less than half of your bitcoins if the price has reached that price, just to make sure that either way (deflate or inflate), you won't lose that much.
If bitcoin drops the price back to 500-600$ and you did sell some of your coins at 1000-1500$, then you didn't lose that opportunity to sell some at that time. The only reason to not sell all your coins at that time is because you're anticipating the fact that bitcoin might reach a higher price, thus giving you more profits.
