I don't think crypto is even close to taking center stage. Not enough people know of bitcoin, not enough people understand bitcoin, and we won't see widespread adoption until we've solved a few issues. How many users does the entirety of cryptocurrency have? Do we even go into the million? I think bitcoin is going to be widely recognized by 2020, widely used and understood by 2030.
I agree with this; no quick mainstream paradigm shift for crypto. Right now to most it's a curiosity at best. Hash up and hodl.
