Anyone that got it right?
My prediction wasn't bad:
LoyceV (Legendary)~
14. How much will Bitcoin cost at the end of 2020?"I'll tell you in January

No really, I'm terrible at predictions. If I'd know, I'd be rich! I still have high hopes for the coming months (after the last block reward halving)."
I know I said I have high hopes, but
damn 
The current price is higher than I dared hope for.
Really?
I hardly understand why everybody is surprised by the price:
14. How much will Bitcoin cost at the end of 2020?"I wouldn't be a PlanB Zealot, if I didn’t take the Stock to Flow seriously. So I take this answer from
digitalik.net: 25,500 USD.
Also be warned I wouldn’t be a PlanB zealot if I take the model as a literal future prediction tool. "
That model has been working since 2010: why should have it been broken on Dec, 31?
The model will eventually break, probably because the dollar itself will, but this is another story...
