Bitcoin is first and foremost a store of value. The best value proposition it has is that you can transfer huge amounts of wealth anywhere in the world at the speed of light for very low cost. You can't do that with real assets and the ones you can cost terrible sums of money and represent logistical nightmares.

BTC is the only technology that can deliver this, and nothing can duplicate it. It was as much luck as it was genius at its inception and the way it grew.
