Life in a fiat world
Almost every price you see — wages, rent, groceries — is denominated in fiat currency. Fiat works because it's legal tender (debts must be settled in it) and because its issuer (the state) backs it with the power to tax. It's a promise backed by force and confidence.
The slow leak
Fiat currencies have a structural tendency to lose purchasing power over decades. The 1971 dollar is worth roughly a seventh of its value today. That's not an accident — it's the result of money supply growth consistently outpacing real economic growth.
💡 Your savings in fiat
Cash in a 0% account loses ~2-3% a year to inflation, on average — more in bad years. That's why 'safe' cash is actually a slow loss. Investors hold assets (stocks, property, crypto) precisely because they expect them to outrun fiat's erosion.
Crypto as a parallel system
Bitcoin and other cryptocurrencies offer an alternative: a monetary system with a fixed, predictable supply that no central authority can inflate. Whether it becomes 'money' or stays a speculative asset, it represents a real experiment in money without a state.
Both systems have tradeoffs
Fiat offers stability and legal backing but leaks value. Crypto offers fixed supply and censorship-resistance but is volatile and young. Neither is 'correct' — a sophisticated investor understands both and allocates accordingly.
💡 The right question
Don't ask 'is crypto going to replace the dollar?' Ask: 'how much of my savings should be in assets that can't be debased?' For many, the answer is a meaningful but measured allocation — not all-in, not all-out.
