I was just thinking about that this year will end up to $1,500 but it was still too early. And after the first quarter of this year we saw the price went up to $1,600 and now at $1,700+ I would not say that $4,000 this year is impossible because the market is becoming bigger but it will take time before crossing that mark.
Until the end of the year, the market may still explode and the price of 4k dollars may not be the limit, if we look at the growth rate.
As I understand Bitcoin price is increasing because its become harder to obtain, but at the end of the day it is just a means of transferring payments electronicaly. So why don't people simply switch to any of the other Altcoins instead of keep pumping the value of Bitcoin?
