For now, I think the price of BTC is unable to return to 20,000 US dollars, because the sharp drop in BTC prices, which has hit the confidence of investors, it will take a long time to recover. But I think in March 2018 may be close to 20,000 US dollars price.
I will wait for the good come back of bitcoin this year. I hope that this March 2018 is the good one and finally reach again at $20,000.
I also think it will go back up at the end of February beginning of March. All these people are just silly and lose their head over nothing. Always thinking Bitcoin will die. If that's how they feel they should just leave.
Always talking about bubbles that people are insane and are obsessed with bubbles. It won't even take long to recover give it a month or so and it will. I just know so.
