My estimate is that no one can predict the price of BitCoin properly because it all depends on market conditions. We will see how the market decides where the price of bitcoin will move until the end of 2018.
If we are talking about prediction, well, someone can.
Prediction, a statement about what you think will happen in the future. It is obvious that someone can predict or guess the upcoming price as we all know that sometimes there are times that might affect the price and might be correct to someone's prediction. How can I say that someone can predict? We are investors, we analyze the current prices and movements and what might happen, based on that we make a prediction and make our move or invest. We predict because that is how we earn as investors.
