Of course people who dare to sell their offline assets to buy crypto assets are people who see opportunities at that time. They can lose, but they can be lucky their crypto assets go up in price more than the price of their house. This is just an example. I suggest don't do this kind of thing, because it's very risky.
This is indeed a risky move, but did you know that the CEO of Binance sold his house for crypto?
And look how successful he is now, it's about luck actually and some are winning to take the opportunity risking everything.
Worth a read my buddy -
