well, it sounds good but I do not think it will happen in the near future, maybe 5 or 10 years from now, because crypto is still unacceptable all over the world but it will definitely be accepted in the end, because nothing can prevent technology.
but I really support it.
You can buy a house with bitcoin now, you don't need to wait for it to be acceptable worldwide in the future. All you need to do is convert your bitcoin into fiat and buy a house.
