$10,000 per bitcoin is maybe possible by 2020 if more countries and enough business start to use bitcoin. my prediction for another few month bitcoin price will around 1600-3000 and 5000 next year.
Hmm interesting, as you said 2020 yeah it can be reach to $10,000 till 2020, but in my opinion it will reach soon because as people taking interesting in bitcoin. So that's why bitcoin is playing role of segWit. So we can say that it will boost more than a past and present as bitcoin improving the disadvantages into pros.
