Thank you for saying that but I don't think that ten years fit the title for an earyl adopter because it ten years, I would probably say that they are in the middle, I think there's a time that is only limited to people who are really early adopters. The scarcity is also amplified by the hype, increase in population and advance in technolgy.
If you consider the diffusion of innovation model, you'll find out that ten years can easily fit into the early adopter period, especially when there is still an enormous room for larger scale adoption. Bitcoin has the potential to be around for tens or hundreds of years from now.
Only a very few percentage of the population have been actively exposed to Bitcoin and fewer companies or businesses accept it. I believe those in now are still very much early adopters.
