It would have really been nice purchasing a house with Bitcoin in my country, but the major issue their is that the people into crypto is not that much, and not everyone is familiar with Bitcoin and how it's nature, that's one thing.
Another problem is the government, your account will get freeze once any crypto related transaction is done with your account because it's not approved by them, today if you ask them, they will deny that they are not against crypto, but our local bank freeze anyone that did a crypto related transaction, and it's because of the other given to them by the government, so at it is now, their is quite a lot of obstacle that will be a barrier if you wan to purchase a house with Bitcoin in my country, all crypto related transaction that we are doing now is strictly coded, not openly, so on that note the possibilities is very low.
