Very simple. He wanted the house, he got the house using bitcoin. He didn't want the fiat. Clear? He got change out of the deal. Again, it's dirty fiat. He didn't want it. Used it to buy the car. Clearer?
I want to buy a laptop so I get a gift card with bitcoin, I get the laptop. What's hard to understand?
If I don't accept bitcoin as payment for my house... you can't buy it using bitcoin... you have to change it into USD and then pay me in USD.
Just because you had it in bitcoin and ride the hype up, and got out on top and then swap it to USD to buy my house... doesn't give it meaning... you're just riding the hype/bubble.
Again, mass acceptance.... not there yet... and will not be there when BTC is at 5000
