it is very difficult to predict bitcoin prices for the next 5 years. Why is that ? you can see for yourself the problems that are happening in china, they forbid ICO, and plan to close the bitcoin trade there, whatever happened, but this is real proof, every bad issue about bitcoin ,, "BOOM" bitcoin price down. which is able to strengthen the price of bitcoin is the market, But in fact it is even bad news that makes bitcoin prices down. Just an expectation from me, hopefully in the next 5 years bitcoin can reach $ 10,000 per BTC
