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.
Actually, I would say cryptocurrency is actually dependent on blockchain technology since that is the technology which it is laid on anyway, but blockchain technology is a technology on its own, and with or without cryptocurrency, it will always thrive.
We all know the rate at which blockchain technology can be applied to a lot of things when used in real life or implemented, most especially when it comes to transparency and accountability which is what would actually be disrupting the way things are done basically in most sectors and in this case, we are already seeing it disrupt the financial sector.
