I think that the behavioral changes it produces on individuals and the positive consequences of those are tremendously underrated.
I mean the typical bitcoiner transformation story. Came for the greed, stayed for the revolution. People stop smoking and drinking, start saving more money and becoming financially responsible, invest more and more in educating themselves, start taking care of the health, accept the fact that everything that's worth takes period of work, etc.
Millions of people doing these changes will eventually have a massive impact on society. And to me, these kind of things are the true wealth that Bitcoin brings. Remember, money is not wealth.
