I don't think buying a house would be a good idea. Not to mention, you have 100% of your net worth in bitcoin?!?! Why would you do that?! (at least the way you said it sounded like that, if I'm mistaken then I'm sorry)
Why do you think isn't a good idea? It is everyone's dream to have their very own house. That's why for me whether the price of bitcoin is going to increase or not, I want to fulfill my dream of having my own home. It's either for me to live there or I am going to use it for business purpose like renting it for monthly profit.
