All this with 0.07BTC that is approximately $9,120 at a price of $120,000BTC which is somewhat a very low amount of money in most countries around the world to afford such a house you displayed over here, this sounds so unbelievable.
The story didn't add up mate
In accordance with what he said because Indonesia with the Fiat IDR currency if it was exchanged with a dollar after the amount of bitcoin converted to IDR (rupiah) was very likely to get a decent home and for some people could not consider no longer feasible, but it had been categorized as luxurious.
Keep in mind, not all regions in the OP country have the same price rates. If in a big city, maybe with the amount of money can not get such a luxurious house considering that each region has a different price variation.
In my area, although both Indonesian, the amount of money is still lacking to be able to get 1 housing unit as displayed by the OP.
A month ago, my brother bought a house in a rural area for IDR 120,000,000, or the equivalent of 0.062 BTC at today's price the house is ready to move into even though it is not new, but it is comfortable and livable... maybe it just needs a little renovation.
This is because house prices in rural areas and big cities, especially crowded cities, are expensive.
So it depends on your choice and the location you desire the prices can vary significantly even though the houses are almost the same in the city, as rural areas naturally have different prices.
