Step by step analysis of bitcoin market, this current year 2019 bitcoin will be recovery its price and reputation. I think bitcoin will be highest soon or later in this running year...
Your prediction is quite appiciatable. But Bitcoin hit 11.8k$ from 3K$ in this year, which is huge. That's why It can't be exactly predict that what will be the cost per Bitcoin by 2019 Dec but i guess btc will remain same as Now (around 10k$-13k$)
I would not want to judge the value it will hit based on its last performance in 2017 because that was a bull run time, but even if there is not going to be bull run this year, I am very optimistic that by December, we should at least be $15,000.
If bitcoin can get to this value by December, then we should expect that bull run will start very early next year because that would be at least 60% of the last value and based on some analysis, we need such percentage to force the market into bull run, bitcoin at that value would not really be a bad increase at all, just that I am not sure completely if the bulls will be able to hold stringer or those who are doing sorts in the market will force it to correction state just like they have been doing with many increases we have witnessed of recent.
