The question in the title can only be answered by humans. No institution, no law, your regulators, or other disasters. Humans must working together, than they can keep Bitcoin maybe alive “forever” (I cant imagine infinity, and I wont live that long). It probably started with human activity, even though CZ said that Bitcoin was invented by an AI from the future. And in the end, it will also be controlled by humans. So far, nothing has been stop Bitcoin, and I believe that will continue in the future.
