Not totally mainstreamed but likely "known". It's the time where people all over the world have the idea about cryptocurrency but doesn't really have the "idea" what does crypto and blockchain do. I guess it will take 1-2 years to be fully mainstreamed since Ripple is donating millions of dollars to top Universities all over the world to have a collaboration to support and accelerate academic research, technical development, and innovation in blockchain and cryptocurrency. It can affect cryptocurrency big time.
