Because your two line shitposts don't make any sense:
there is no limit when to save as long as we can save whenever and any age must save because saving it for the future by saving we can have savings for the future ..
as long as bitcoin believers and many who use bitcoin during that bitcoin will survive, because something that depends on the person when people are still using bitcoin and still circulating then as long as it will survive ..
I could go on. Stick to your local board if you can't speak English.
