Yeah, I agree that renting is a more flexible life, and it sounds great.
Until you realize that you are basically allowing another person to have full control of where you live.
They can at any point kick you out.
That kinda goes against the idea of Bitcoin, where you basically take care of your life, and don't depend on other people.
I think owning your own home is an important thing that is not happening too often for the new generations because the prices are going insane.
Renting provides flexibility, especially if it's a furnished apartment; you can pretty much move in the span of a few days. However, that doesn't mean that if you're a homeowner, you have zero flexibility. You can simply rent it out; the housing market is nuts; you'll find a renter within a few days, enabling you to move using the money you're passively receiving. Comparing Bitcoin investing with real estate makes no sense; they are two completely different sectors; both have advantages and disadvantages; real estate, though, provides a lot more options in terms of versatility, such as renting, flipping, or living in it.
I personally would prefer owning than renting; you have much more freedom in your own home, and you don't have to interfere with unpleasant homeowners who don't care about you or the property they are renting. Bitcoin investment is a completely different sector that shouldn't be compared to, you can always pursue both.
