On a long enough timeline, the Difficultly really only goes one direction

I'm not sure about you, but that is one strong network that keeps getting stronger.

Yes there is a brief dip around the halving, but in due time it will be making new highs yet again.

The network just keeps getting more and more secure as time goes on.

I can't imagine what it will look like by the time the next halving rolls around.
