Some people like the Brazil Central Bank Chief called Bitcoin a Bubble & Pyramid Scheme, how can the bitcoin industry prove this wrong and make sure bitcoin never ends but grows bigger?
By the way, he correctly noticed that this is a pyramid, the resources of bitcoin are already at a minimum, the main profit of the creators or who first came. Others are still collecting crumbs, which may soon also disappear. Of course this is a pyramid and soon it will end with a ban all over the world.
