The first 50 Bitcoin took 10 min to mine.

The last 50 Bitcoin will take 52 years.

The value of 10 min is relatively worthless, and so were the coins at the time. But the value of 52 years is far higher, and so will the value of all coins be at that point.

Bitcoin's marginal cost of production, driving the value of every coin in the network with it, continues to increase relative to BOTH time and energy. Providing a perfect store of the value of both.

The world isn't ready, but it's happening anyway. Bitcoin isn't asking permission.
