I think its a funny question. This is speculation sector but speculation should have a limit mate. Well as to this topic,, maybe it will happen in future cause anthing is possible in this cryto world. But i don't have any idea right now about it. Let's see when it will be happen
Is there really a limit to speculation? Everyone obviously is free to stick out their opinion whether they sound ridiculous or not. It is fun sometimes, when we imagine something like this happening one day and then wondering what one would be worth by then.
We cannot predict quite sure, but like you said, I am not sure something like this can happen in few years to come. Probably in the next few decades, but since we cannot predict the future and we do not know how fast bitcoin can grow, then we will just keep guessing.
