Why can you say that? Bitcoin/Cryptocurrency is everywhere currently where there is less than 50% of world adoption, yet you can see it on the news, sports, and movies.
When you say there will a huge mass adoption in the future, then it's more likely to be seen on the news on a daily basis just like how the dollar is fluctuating today.
However, I'm afraid when that time happens most of us here is either very old to handle our crypto investment or worse dead.
