This depends on your location. Is there some place where if you buy a house, or maybe regardless of what you own, you will be taxed on it? If your location is like that, then I will say you should go bitcoin, and then maybe when you are balanced enough to pay all the taxes, you can think of buying a house. But if you don't have enough money to do that, then I think bitcoin will be better. You will cash out from your bitcoin investment after a long time, and by then you can buy a house.
If not for the taxes and other things that you, as the owner of a house, will be paying because you own it, I would have said buying a house is also a big asset that one can have.
Owning a house IS owning a big asset regardless of the taxes and everything one has to pay, besides, buying and holding Bitcoin so that one can buy a house in the future doesn't make things any easier because even if the price of Bitcoin goes up and the investment made gives good returns, the prices of housing and real estate wouldn't be stagnant during that time and a house that one can buy for maybe $200k today will be worth $400k or maybe more within 4 to 5 years because we know properties keep getting expensive over time due to the increasing population and high demand for housing.
So, in my opinion, if someone has enough money and can easily afford to buy a house, making sure that the money they will spend on it is directed for it which means they aren't holding up on anything else, I would say they should go for it. A person should have separate funds for each purpose. If you want to make investments, you should be saving money for that separately when you have a good source of income, and if you don't have a house of your own, you should be saving money separately for that. Don't mix things up.
People say it's better to rent than to buy a house due to the high prices of housing and property, I would say there is a very big difference in living on rent and living in your own house, and only those who had their own house but then had to sell it for some reason and are now living on rent can understand this.
Owning a house is good and it is preferable in places where the expense on maintaining a rented apartment is more expensive that no one having a personal house. Also come to think it the price of Bitcoin is not guaranteed that it will be so high in the newest 4 years. But i assure you that the price of building a house or buying one will be a lot more expressive than what it is today. Bitcoin is volatile asset, it is good for investment and profit but we all know that there are bull season and there bear seasons. No one knows when these seasons will come that is why you cannot entrust all your wealth into Bitcoin when you have an emerging plan.
