So, it´s a question of an assumed hashrate on which an assumed difficulty is based. Then big mining operators play that like a fiddle to fleece their investors. Small wonder that nobody in their right mind takes this mess seriously. Nonsensical production of a produce that has no volume  on two-bit exchanges and constantly falls in price. It totally stands to reason. But the more confidence in this nonsense tanks along with the price the more it is supposed to be worth in future. Good luck with that.
