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.
That's a fair point. The most significant part of this observation though is "Decentralization". The price cannot be predicted in a decentralized model. Many factors can make an impact in the actual price and end up in the green or the red side. Personally, I have stopped reading speculations about the price and try to make an estimate based on historical data. Maybe this is not correct as the chains keep evolving year by year.
As far as I know, there is no reliable way to predict the price of Bitcoin, so your own estimations can be as good (or as bad) as any other estimations made by the so called experts. At least there will be no one to blame except for yourself in case of a wrong prediction. I think you are right about evolving, and that's why the situation for crypto is better now than ever before, and we can hope for much wider adoption in the future, which inevitably will lead to rising in price of the most established coins. But that's me, I know that some people don't think that the price should necessarily rise in the case of wider adoption, and I respect their opinion too because only time will tell who was right about these unpredictable, in a scientific way, matters.
We cannot totally predict what the next exact price of the bitcoin. The value of the bitcoin is now become so unpredictable and it is due to its volatility. Even I using different tools in technical analysis, I can't still have a right prediction.
