What are long-term sustainability of fiat systems?

Fiat systems are like paper money that people trust to keep its value over time, but how long that lasts depends on how well it's taken care of.

Imagine you have a piggy bank full of coins, and every day you add more coins to it. That’s like a healthy fiat system, it grows, people feel safe with it, and it keeps its value. But if one day, instead of adding coins, you start taking them out faster than they come in, the piggy bank might get lighter and lighter.

That's what happens when a fiat system isn’t sustainable long-term. If too many people take more money out than is being added, like spending more than is earned, the value of that paper money can drop, just like your piggy bank would if you kept taking coins out without adding new ones.

A fiat system stays strong when:

• People keep trusting it (like believing your piggy bank will always have enough coins)
• The government or the people in charge don’t print too much money all at once (like not filling your piggy bank with fake coins)

If those things go wrong, the system might get shaky, like a piggy bank full of holes.
