It seems to me that anything that the world system is fighting against is a safe bet that it's NOT the currency of the Beast. Crypto currency is decentralized, so there is not central authority to oversee it.
Prophetically, the Beast is "given authority" by the dragon. Cryptocurrency takes authority away from the system and gives it to the coin holders to self-regulate in a secure and transparent manner. The Beast system HATES unregulated digital currency. The beast believes that all authority belongs to him.
People worshiped the dragon because he had given authority to the beast, and they also worshiped the beast and asked, "Who is like the beast? Who can wage war against it?" Revelation 13:4
He was given power to wage war against God's holy people and to conquer them. And he was given authority over every tribe, people, language and nation. Revelation 13:7
