I don't know what you mean though, if you have the money to buy a house so go get it I think it's the best decision you will ever make in your life. Not just for you, but for you wife and kids. So it doesn't make sense to rent just to invest your money in bitcoin. As what we are all saying, invest what you can afford to lose, so that philosophy you should follow. So after buying a house, then maybe if you still have some capital then invest, go work and save more and re-invest again and then wait for the next bull run to cash out your profits.
