I don't like the commercial it's boring and not creative.

If you have 5 Bitcoin, which is currently worth about 500,000 USD , trading it for a house is probably the worst thing you can do. That 5 Bitcoin will be worth much more in the future.

So what do you do? I guess if you really want to buy a house you should take out a fiat mortgage and keep that 5 Bitcoin. Ya you will probably pay double the house price with interest over 30 years and a big chance that in 30 years, Bitcoin will be the dominant currency and real estate is most likely never to appreciate anymore so you're still on the hook for that money but since you still have that 5 Bitcoin you could easily pay it off.

You could also just rent but the problem is if you have a wife and kids renting a house is actually more expensive than having a mortgage over the long run but living in a apartment with wives and kids is not ideal and also you still need to work and can't move to the country and buy a cheap home.

So many problems whichever way you go but I'd say do everything possible to keep those 5 Bitcoin.
