You are still considered as an early adopter even if you join today because the adoption stage today wasn't even reach 25% of the total population in the world. Even if you survey your friends and people you know, you will realize that we are still far.
We have not even reached 1% and I have my doubts we have even reached 0.1% of the human population and when you see those numbers and the huge potential of bitcoin then it is no odd to think of us also as early investors, what it happens is that the level of adoption we are expecting has not happened yet but there are high chances it will eventually happen.
