I'd think that crypto currency and blockchain is independent with each other. Blockchain technology is just a means of distribution, record and other good stuff that could be applied to other things not just crypto currency. I just hope that we see more and more innovations on both crypto currency and blockchains.
in my opinion the two things are interrelated cryptocurrency is one of them innovation as well as product of the blockchain itself, if only blockchain is released without crypto, then it is certain there will be no enthusiasts, because they think why not use email or ATM machines to make transactions
