I love BTC and have what I believe to be a nice healthy stash. However, to suggest that the property market might crash seems a little bit optimistic to me. I also live in the U.K. And had a property that I sold sometime back and now wish I had held on to it since it value has since tripled from when I sold it. Everyone needs a place to live so I believe that there will always be a demand for property. Only scenario I envisage where property wont be needed is if there is a mass exodus from said country and I just can't see that happening in the U.K. Within the immediate future anyway.
Returns are, for the moment anyway, far better in BTC but the volatility of it makes me quite nervous at times.
Anyway, best of luck whatever you decide and it will be interesting to see how it all pans out.
Demand by itself doesn't mean much if you can't afford something. If there were a credit crunch, prices would drop, as few can afford a house without a mortgage.
Get the Lite to the Moon!!
Gotta say, the chikun is the most interesting thing I've seen for a month.
