if you have 40 bitcoin right now, i think you can buy a good house now
what you're talking about 40 bitcoin is only $16k, you cna buy a garage at most, not even a good one
no way you can buy an house with that amount, here for example you need 40k for a good condition one(2 room) 40-50mq
all depends on the price of bitcoin. if bitcoin really go above $1000-5000 you certainly do not need to have a lot of bitcoin to buy a house.
so I would say 10 bitcoin is enough to buy a house

Its not to predict but its unlikely that the bitcoin will rise to 5000 dollar this year.
I think its possible to buy a house but it will take some time.
It would of course be pretty cool if you buy a house with it.
but how about tax in bitcoin ?
in my country if you want to buy a house, you must have bank rekening, also registered as a bussinessman, etc.
are you sure in future the goverment will allow everyone to buying house with bitcoin ?
