Bitcoin is designed to continue to exist even until 2100, so what makes you unsure about Bitcoin?

While we may speculate about its value in the future and there is no concrete certainty regarding this matter, the system has been clearly outlined from the start: Bitcoin will continue to operate until the point where it can no longer be mined by 2100. It will remain that way because nothing can stop Bitcoin, and even if it were to run out, it would likely continue to operate (and it is likely to do so).

Therefore, in the future, the situation will remain the same, with the main difference being the value and price, which will inevitably be different from what they are today.
