It's already being discussed in another thread. His bitcoins appreciated in value so he had to spend less of them to buy the house. The risk he took paid off. If he had lost 20% it would have been the opposite but the opposite doesn't mean he "lost 1.3m" because that doesn't make sense. It's not how profit works durp.
some people get money and some people lost his money at bitcoin tradeor at unstable bitcoin price. this is the risk using bitcoin to pay something, thats why i recomended to use bitpay, and convert it to US dollar real time.
thanks for your attention, better i lock this thread, and continue disscuss at other thread
