SMTs.
There are hundreds if not thousands of sites that have ten million plus monthly active users. A site like SeekingAlpha, that is far from mainstream, have over 15M per month.
It doesnt take too many of those to adopt SMTs before we are over 100M.
Suddenly, people are showing up and seeing tokenization, which is powered by the SMT protocol.
That is tens of millions who will have the opportunity to get rewarded if they so choose to participate.
