Personally even if BTC goes to 10 000$ I don't have enough of them to buy a house. I want to buy a house this year, and it will cost about 270BTC at current value. If BTC was 10 000$ it would only be about 30BTC, but I don't hold 30BTC. I could buy 30BTC right now, but I think it will take years for BTC to go to 10K, if it ever happens, and I want the house right now.
I will keep several BTC, so that if it goes to 10K I'll be happy anyway, maybe buy me a Porsche with it !
Wow, you want to buy a house worth $300k? That's a big house, and a lot of money. If I were to buy a house it wouldn't even cost half of what you're paying. Houses in Europe are much cheaper, you can have a decent, spacious one, for just $100k. If you want to buy a good car don't choose a porsche, they are bad at turns and it's easy to lose control at high speeds. It's not very comfortable, expensive and bad to race with. Not worth the price.
