I married my husband who was already living in his van, brought him to Sweden for 6 months where we got into bitcoin, and then we moved back into his van for over 3 years.
It was great! Then last year, we got super cheap land and a motorhome, so our "rent" is under $35 per year in property tax, and we have solar power, and there's a free place to get water.
So, even if we upgraded to a motorhome, our expenses are extremely low. It has allowed us to eat at home instead of eating out, and now we can work from home, and we actually do earn most of our active income in sats! 😎
