BTC will go up 20.000$ in 1 month.
Price will be 70 k end of 2018.
That speculation was hard to meets in the following months, even how fast bitcoin value raised up I think it enough to touch $80,000. As I view now in the market I think it took a long period of time before achieve it, I was challenge bitcoin in 5 years if their amount cannot touch $100,000 on that period I guess they have no enough ability to erase fiat in the world.
I believe that bitcoin have no enough resources to give $80,000 to the users, however we can see it before or after 2018 if they can touch it.
