This prophecy speaks of the death, or at least the collapse, of all Crypto currencies, including BitCoin, Dogecoin, LiteCoin, and others. Basically everything that's a crypto currency right now is going down. This doesn't mean that others won't rise up on their place later on down the road. What it's saying is that the current crop are going to collapse, and either completely go away, or simply take heavy damage that will result in their complete, or majority abandonment. The ways that this will happen have been predicted to be several things, including the Fiat state of cryptos (ie, they have no backing like gold or silver, or even a government), as well as a major attack that brings the entire system to its knees, causing them to become unusable, worthless, or both.
