5 year is a long time which anybody can not predict. There are some breakthroughs each year and maybe in 2 or 3 years later there will be another currency, or another trend that will take place and bitcoin will drown in forgotten, or there will be some advance in the market and bitcoin will rise stronger than ever. Only time can tells.
More and more people will come to know about bitcoin and hope that the investment capital will also increase due to which the price will also go up. The situation may be different from what I mentioned above because this is cryptocurrency world and anything is possible here. It is right that 5 years is big time and prediction for such a long time is not possible.
