Well, I have always thought to leave work after earning enough money for living the rest of my life, not caring the retirement. Nevertheless, If one got used to work, it might be boring after at one point, supposed they r at mid-age.
The idea of living off crpyto sounds sensible, but risky at the same time. We can see it could happen in few years, who knows.
Your friend is lucky. People in my country are already ready to have a job even under min. salary. Changing a job three times in a year, interesting.
A lot of young people don't seem to want to get used to work - yet they still want all the money benefits.
Living off crypto is far too unstable for me at least - I would need to be a whale of monumental prportions to pull that trigger.
As said, they are privileged, but might not know it.
