I believe that bitcoin is underestimated, I do not claim that it should only grow! But I'm sure that the future is for him! crypto currency in general, and bitcoin in particular - this is digital gold,
The previous year the price of bitcoin had exceeded the price of gold precisely in December of 2017, but when it entered 2018 the value of bitcoin continued to decline to the lowest level, which is above $ 3000. Based on that experience I'm very optimistic that bitcoin will set a record again ( exceeds the price of gold) the second time, at a time that we cannot yet determine.
