To expand on a point I made earlier, I want to relay a story from history:

------
In World War II the allies relied heavily on bombing the enemy to try and turn the tide of the war. However they were losing a lot of planes from ground fire and air combat. When many of the planes returned, they were often shot up so badly it was a wonder they could fly at all.

"We need to reinforce these planes with armour" said the leaders in charge. But the engineers had a problem "If we put too much armour on them, then the planes will be either too heavy to fly or burn too much fuel to be able to make the trip".

A mathematician named Wald was asked to catalogue where all the bullet holes had torn through the plane. He produced a diagram that reflected something similar to this:

The plane on the left represented the undamaged plane, and the plane on the right was where the damaged was being recorded. The superiors said "ah, we need to reinforce the wings, nose and tail because this is where the damage is occurring".

Wald said "I'd reinforce the areas where there are no bullet holes".

"What?" they said incredulously. "But that's where all the damage is!"

"But Sir" said Wald "these are the planes that made it back"

As the obviousness of Wald's observation sunk in, the engineers began the task of reinforcing the remaining planes

If cryptocoins are going to win the war and become a viable currency, we have to stop focussing on the holes and start seeing the areas that truly need to be reinforced.
