The deflationary nature of bitcoin which will appreciate in value  so much say a million dollars per coin and beyond, that it discourages spending and encourages saving..

Every merchant across the globe will wish to have some bitcoin and hence offer their services for bitcoins to the point that they accept only bitcoins for their products and services.

So ultimately any hardcore Hodler cannot continue Hodling forcing to spend to get daily bread as well as luxury things, but will think before spending twice!

Those merchants who offer lowest price will survive in the market.

 all these leads to responsible spending, efficient market dynamics and above this the democracy and Goverment will become open as all their transactions will be available in public, this roots out corruption.

Thus the world will be a better place and everyone will live happily ever after.
