Blockchain, if somehow you didn't get a chance to hop on it, is a technology game-changer that dazzled the world with cryptocurrencies like Bitcoin and Ethereum. Though I can't really comment on the future of cryptocurrency at this juncture, the underlying technology (Blockchain) looks very promising to me for the long-haul. That I could say because Blockchain provides what today's generation expect from the digital world - an open, decentralized system which is super secure, efficient, and transparent.
