Just like other saying, but for me, nothing will believe that bitcoin can defeat gold. Gold is a gold, nothing can defeat gold. Bitcoin value can defeat gold, but the gold value will still remain on its value, and cannot be changed. Gold value is stable, bitcoin cannot defeat gold because we cannot predict what will be the cost in the future and what will be the value of it ? We cannot say but it can be, we will just wait for what will happen on bitcoin value and gold value.
