I do think this speculation is happen on 2018 or some time. I think we will reach to 2000$ and above value on next halving. Before we can see multiple fluctuations in the price value. I hope we need till happen and check it. Many of the speculations are not happening in real.
the next halving is about 3 and a half year in the future. so you think it will take about 3.5 years to only rise 2x?
i seriously doubt it.
price has been rising with good multipliers over the past. in 2015 it went up 2.3x and in 2016 it went up 2.5x and before that i mean the years before MtGox pumping bitcoin and ruining everything, price was going up 2-3x every year.
There is no doubt that every years price of bitcoin increase significantly, during fisrt 2016 the price around 400 - 500 dollars ( with various fluctuations ) and know bitcoin price is 1000 dollars. I am sure that next years the price is growing up agagain rather than now
