Now it seems about 2 bitcoins for one house. But it reallly depends on place where you want to build and, of course, how big is the house which you need 
.
.2 BTC for one house? In which place this exists?
In my country I need 15 BTC to buy it. If I can do it or 2, then I am going to move on your country.
Seriously ?15 btc to Buy a house?lol why need luxurious house?
He wanted to have decent living so maybe in their place 2 btc is enough,and actually depend in which place in every country .
Even in US there are cheap houses depend in location.
For this money I can buy a land around 50m2. And I start build for myself
I asked for donation and that mean I can not ask a lot. For sure to build house with spa, bbq, big garage, pool will need much more money
Right now I am building a small apartment which I own. Still need 5k usd more in that
