I don't believe any predictions. Bitcoin is the king of cryptocurrency and it can show any order of prices. Who cares? Now the price of bitcoin falls to $ 6,000. You left bitcoin? Now the price has risen to $ 7,500. Has anything changed for you? Believe me, nothing will change for you, even at $ 50,000.

you can read history bitcoin price, in early 2017 bitcoin price under 1000 dollar
but in end year 2017 bitcoin price incraese to 20k dollar,
