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.
