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 agree , but i think if this ''crash'' hurt your confidence in bitcoin you didn't know what you were getting in to. But bitcoin has gone from $1000+ tot $150 to go to 20k. So keep that in mind.
the chance of bitcoin to go up and touch 20k back is big enough, even that is not impossible the price will far exceed that number.
we know alot of new people will join bitcoin economy, thats how the capital market value and volume becomes more sky rocket.
