You can buy a house, then take a loan against it and buy BTC with that money. Then you still have the BTC whatever happens with the house, the bank, and the country 😁

Sounds tempting 😉 Unfortunately this won’t work (at least in the EU). The bank will only give you a loan when it sees the signed contract for the house purchase and all necessary insurances. It’s part of the loan deal.
If I could buy a house first, without the bank, why would I bother at all? Also in that case, I would just go all-in for bitcoins and buy a house after the nearest halving.
