Of course it does have a future at all everything that has been helpful and good to all of us deserves it. It is now a well-known internet currency and no doubt that its popularity will keep on increasing and it can be known for the next few years, even though we are still few in this society I know that one day bitcoin will be used by many countries and users.
Yes, think about who bought BTCs 5 years ago, made a lot of profit in BTCs and now it's already possible to convert to fiat and have a mega profit. Now think in the next 5 years how much will be Bitcoin pricing, a mega profit for who continue holding and waiting for the next big jump in the price. As more and more people start using it and more Bitcoin be mined, the currency price will continue increasing even more.
