Ampleforth is a special crypto that can increase and decrease the amount of Ampleforth available on the supply without affecting the overall proportion of Ampleforth owned by someone. For example real money is elastic as you can make more of it but by doing so increasing the amount of cash printed you dilute the overall value as the more of it that is  available the less valuable it is!(inflation)

But with crypto currencies like bitcoin are non elastic as you can't create more bitcoin than is already available so the price just increases with demand.

Ampleforth is both elastic and non elastic as the amount of Ampleforth can change over a daily basis without diluting the supply and you the Ampleforth holder will always hold the same proportion regardless of the supply of Ampleforth that day so it makes Ampleforth like fiat currencies where they are elastic but doesn't dilute the overall supply like fiat currencies.

where as bitcoin is non elastic and therefore not dilutive. Ampleforth is a unique crypto that can be elastic but non dilutive at the same time.
TO EXPLAIN CLEARLY

AMPLEFORTH SUPPLY CAN CHANGE ON A DAILY BASIS WITHOUT AFFECTING THE OVERALL PROPORTION OF AMPLEFORTH YOU OWN!

 WITH REAL MONEY THE MORE MONEY THERE IS THE LESS VALUABLE IT BECOMES.

THIS IS NOT THE SAME WITH AMPLEFORTH ITS A UNIQUE CRYPTO THAT CAN CHANGE ITS SUPPLY ON A DAILY BASIS WITHOUT AFFECTING THE OVERALL PROPORTION YOU OWN! THERE IS NO INFLATION!

So if your an Ampleforth holder you can't be diluted by supply inflation.

Ampleforth uses smart contracts to do this smart contract automatically increases and decreases its money supply. And it accomplishes this without the need for a central bank
