As a trader, my views on this year 2019 about the price of Bitcoin is very unpredictable due to its volatility were We don't know when will goes up and down its price value. But I think before end of this year Bitcoin will reach at least 20k$ each, this to good to be true and realistic to be happen as well.
Yes, we don't know exactly how long it is going to take for the Bitcoin to reach $20k but today the price of Bitcoin is very close to $11k. According to your prediction by the end of the year, we are going to see some bullish trend which will surely help all other altcoins to increase their prices.
Exactly, the price went up to $10,900 in a span of like a days from $8000 so I would say it is not impossible that the price will reach $20,000 by the end of the year as per predictions, but we still can't tell because as we all know bitcoin may drop rapidly due to some factors. I just hope it will not drop very low like what happened in the past.
