If you had $100 to donate to a public good or charity.
You could instead buy $100 of a coin that donated all trading fees to the charity.
Now you still have $99.
In 6 months you may have more. You may have less. You won't have $0.
Your $100 buy has generated more volume. Which in turn can trigger more volume.
Now $1,000 has been raised for the charity.
