who know bitcoin will become in 2018 i think its not possible it become 50k USD
There is obviously no guarantees of where the bitcoin price would be at next year, but i really don't think that 50k USD is very likely at all just like you think. There is a slight possibility IF a major economic collapse happened overnight with the fiat economy but imo that's probably not going to happen this decade.
However if you lowered the figure to $10k next year, there is a real possibility that might happen.
I'm predicting $5k end of this year, $10k in 2018.
But honestly I think 2018 is gonna be the year when bitcoin hits the main stream investors. Institutional investors and whatnot. Right now bitcoin is just this weird thing to most people, they think everyone in bitcoin is gonna lose all their money and they would never invest in it. But investment companies seem to be getting ready to start diving in to bitcoin and allowing people to invest in bitcoin through them. I think that will start taking place over the course of 2018 to a decently large degree and I think that could lead bitcoin to have another year like 2017 in which it increases by several fold. Maybe hitting $20k in 2018. That'll be the very beginning of mainstream adoption of bitcoin as the price booms ever higher into 5 digits.
That could be possible. I do think that bitcoin is likely to hit $5k at least by the end of next year, i'm just not sure whether it has enough fuel left in the tank to triple in price in one year again, repeating this year's phenomenon.
