for now bitcoin has reached more than $ 5000, and the development of bitcoin selling price from 5 years ago until now is growing very good, maybe in the next 5 years the the selling price of bitcoin will reach about $ 15000 - $ 20000 and it can improve someones economy from poor become better in the next 5 years
As no one can be so much sure about bitcoin for a single day, therefore i think it is not so easy es speculate about the price of bitcoin before 5 years, My personal view about the price of bitcoin will be that even after 5 years bitcoin price will be increasing continuously because even after 5 years peole will be adopting bitcoin as a currency and will be welling
