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.
well i can agree with your personal decision to an extent because we all have different plans but base on what I've been taught and with the little of my exposure in finance and economic planning, i believe it will do more good to invest on an asset that in due time will replicate it investment capital back to the investor, house is good and bitcoin is as well a better option, but if we are to rightfully consider the scale of preference we will see the need arising to go for bitcoin first and any professional business expert will always advise the same except if the person in question decided to go with buying of house first.
