You know you have something great when the second order derivative is positive.

That is, a compounding curve of use.

That means the market is pulling it out of your hand.

The more people that have it, the more people hear about it, and the more that people want it.

The curve is the most important part that shows this "pull."

Even a small absolute number with that curve is notable, because it grows so quickly that it will be large soon.
