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
I'm in the middle here, I mean it could be true, or it could just be a made-up story. But given that he mentioned IDR currency, it means he is from Indonesia and I think that amount of money is really big and could indeed buy a decent house like the one he uploaded in this post if he is from Indonesia.
Compared to where I am, I have to agree with you that this is just possible made-up story, because that kind of house here in the Philippines is approximately $18,000, or around 1,000,000 PHP.
It's possible that someone might sell such a house here at that price, but it would be extremely rare. And if someone did sell it at that low price, it would surely be sold immediately.
