10 years is very long. I don't know if there is somebody who really paid close attention to it. Perhaps some generalizations will do. Generalizations like Bitcoin must have already crossed $100,000 by that time is probably safe and fair. I'm still not 100% sure of it, but with how things are doing right now, I'm 99.99% certain on that prediction. But you know that things are always uncertain and unpredictable. We can't even be 100% sure that Bitcoin is still alive 10 years from now.
10 years to a human's life is a long time, but when comparing bitcoin to gold or fiat, bitcoin is nothing, so OP's doubt about bitcoin's existence is understandable. But such is life, opportunities always come with risks, so those who are willing to take risks will receive the rewards they deserve. If bitcoin has become as clear as gold then the opportunity is over for us. If we want a lot of profit, we must accept the cost of our safety. It's the law of life.
