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.
We will be in the 2nd half soon, the bullish trend we've seen in the first half will continue in the 2nd half, it's build a bullish momentum and it's hard to stop that, just like the last year when momentum was bearish, we will see a different scenario this year, that's for sure.
