Approx. yes, it may reach $20,000 if only we can maintain the trend. But if we dump more, just as we saw today from 10k+ to 9.8K... it might be hard to really reach 20k.
A $400 drop in the price in a single day isn't exactly a good indication of what's to come in the upcoming weeks or months. In fact, such a small pullback could mean that we're bulding a strong floor before testing 10k and above very soon, so if there's a bigger dump, then there'll be some support around the current prices (9850 at the time of writing).Also, these sort of price changes are still within the range of what many consider normal fluctuations in the cryptosphere. All in all, it's still very likely that we'll see 20k this year.
IMO it will be very hard for bitcoin to reach its ATH during the next 10 months, it would represent +100% from the current price, it's a huge amount.
Moreover I don't understand why people are talking about 2017 here
There was no halving in 2017!
