It's not a matter if it will die.
All curencies die. Always have. Always will.
It's a matter of HOW it dies.
Unlike physical fiat currencies in a system without public ledgers, the open ledger STEEM allows the people to track the "flow" of money.
That in itself will allow for real-time monitoring of inflation/deflation.
All money systems collapse, but a money system in which the actual users have the ability to monitor and exercise personal control over has never existed.
Its gonna get interesting, one way or another.
