All is nice but $20k is a bit to much.
I doubt bitcoin will reach $20k in 2017 or even 2018, most possibly not even in 2019 but who knows. I think max for this year is $10k, but most likely $4-8k.
We are ofcourse talking about the ATH. After it will be reach price wil slowly started
declining to Fibonacci point. I wonder how can mathematics predict its price. Of course using probability we can predict "but prediction" is the same for "not really sure". And how can fibonacci point point its price?
Because the market is not predictable, there are millions of decisions that is happening there that even formulas can't predict that easily.
