Many people see Bitcoin as an investment and nothing more. They give Bitcoin a business approach and will always project profit which will lead to speculations about the future price of Bitcoin. Just like OP rightly pointed out, Bitcoin price cannot be capped because it has the potential of getting to any price in the future. A few years ago, most price predictions were $100k, and Bitcoin has broken that barrier. So we might start seeing another prediction and I am sure that Bitcoin will still exceed it.
