If i'm gonna compare something that is not ending, we call it perpetual motion. Perpetual motion is motion that continues indefinitely. If we compare this to bitcoin, we must make sure that bitcoin is constantly being supported so it does not stop. We must also not disrupt the cycle of what bitcoin is doing and just accept whatever decision the developers make. If we support and not abuse this cycle, i think that bitcoin would never end. We must also take part to its advancement of security and we must not be careless.
