Sorry for this naive question. But I always have this doubt in my mind.
In my opinion, it should not since Blockchain is engine and Cryto is fuel.
Anyhow, I am afraid that I might be wrong.
Cryptocurrency in this Cryptonomics seems promising but lacking of adoption I would need more advice from your guys.
Yes Blockchain will survive as Cryptocurrency is an application of Blockchain technology.
Blockchain technology Has several use cases, among which are general administration, medical record-keeping, education system, and digital identity cards etc.
