Wow, 5 years? At the present (today) level of technology, human knowledge is doubling about every year. We are in the midst of a exponential explosion of technology, fueled by advances in machine learning and artificial intelligence, so in say 2 years, knowledge will be doubling every few months. Soon, knowledge will double every day.
To answer your question, in a few years bitcoin will most likely be worth several thousand dollars, if not hundreds of thousands of dollars.
My point is that so much could happen in ten years at this point in human evolution. We may be using a new type of currency that we cant even imagine now.
And what is the value of bitcoin if its price is predicted at this level? I can understand why gold or diamond is expensive, but bitcoin should have its own special value.
