Do you? I believe yes, after some years, if more people get into bitcoin, the price will stop somewhere and it will change slowly.
No, it won't happen for I think even for another 10 years. If more people will get into bitcoin, I doubt the purpose is because of its usage but rather to expect a profit in return.
Bitcoin is so far treated mostly as an investment and not as a currency. That practice is running in the system for over 10 years.
Because of that, we just have to take advantage of what bitcoin is giving us, whether as an investment or currency. Fortunately, we can use bitcoin as how we used fiat. Better to see it like this that while enjoying the advantage of using bitcoin, it also giving us an opportunity to make more money.
