We think our money is safe forever, but history is full of currency collapse events.
It happens when a government prints so much money that the public loses all faith in it. This leads to hyperinflation. We saw it in Germany in the 1920s (wheelbarrows of cash to buy bread). We see it today in Venezuela, Lebanon, and Zimbabwe.
When the money dies, society breaks down. Savings are wiped out overnight. Hardworking people lose everything simply because they held the wrong paper.
This is not an accident; it is a mathematical inevitability of fiat money. Every fiat currency in history has eventually failed or lost its value.
Bitcoin is the lifeboat.
Because no government controls it, it cannot be hyper-inflated into worthlessness. When a local currency collapse happens, people flock to Bitcoin to preserve what little wealth they have left. It is an insurance policy against the death of money.
