The medium of saving property is the most important character of bitcoin. In a fiat money inflated world, there is no reliable long term medium of saving: House will depreciation, gold is not convenient to use, bond have risk of default, stock will crash when recession strikes ... Bitcoin is almost a perfect store of value due to its technology advantage and limited supply
In the future, when bitcoin becomes the medium of majority people's life saving, the value of bitcoin will still keep rising, because there is no limit to the amount that people can save. Maybe for 1% of the rich people, they have already saved enough, but 99% would still like to save for the future (Saving does not mean cutting spending, it is just a sign of very high productivity: You can't spend as much as you produce, so you save the rest into bitcoin). This will also solve today and future's problem of over production
Bitcoin will have the highest credit rating on the planet: Even a country/government can disappear, but a network protocol will not
Some massive generalisations there not to mention just plain wrong statements.
What country are you living in where property prices consistently depreciate?!
Housing depreciation is the cost of physical maintenance (paint, plumbing, new appliances, new roof...) Overall, the price generally appreciates despite this due to persistent economic inflation. If Bitcoin were a comparable asset to a house, both would appreciate, but the Bitcoins would cost less to maintain since all you have to do is store them electronically. Thus Bitcoin would have a minor advantage over housing in that regard.
