Before thinking of buying a house, lets focus on the price today, it is playing around $400+, it means we really need a bigger amount of bitcoin before thinking of buying a house... Lucky are those first adopters, I'm sure they can afford a house and lot now if they are still keeping their coins..
Ya it is right at the current price you will be needing more than 1000 btc to achieve your goal of buying a house. We cannot say that the first adopters are lucky because they also wont be knowing what will be the future price as the btc price have gone to up high $1000 and then it fell down think who was holding that time and thinking that it will go more up and then will sell and now when seeing this price will be crying of not selling in $1000. so price is not important it is quantity of bitcoins you have and fullfil the wish whatever the price is as the current price is yours and future price cannot tell.
