Bitcoin should not be a lifestyle, but simply, normality.
What is normality? Don't Trust, Verify.
Check everything for yourself and live your life on your own terms, not by doing what others expect of you or want to impose on you.
In this respect, Bitcoin can't be a lifestyle, because all Bitcoiners can have very different lifestyles since everyone lives on their own terms. That's the point, anyway.
On the other hand, from time to time, commonalities emerge between Bitcoiners.
To name just one: a frugal lifestyle, because with Bitcoin you refocus on your real needs, and stop giving in to the consumer society that pushes you to buy things you don't need all the time.
