Three Ways to Measure Wealth: Dollars, Gold and Bitcoin
This new page compares the same assets from 2015 through 2025 using
three different measuring sticks: Canadian dollars, ounces of gold
and Bitcoin. The charts show how an investment can appear to rise in
dollar terms while looking very different when measured against
scarce assets.
It also discusses inflation, expansion of the money supply and
practical ways citizens can try to protect their long-term
purchasing power.

The basics
What Is Bitcoin?
Bitcoin is a decentralized digital monetary network that permits
peer-to-peer transfers without requiring a bank or other central
intermediary. It began operating in January 2009.
Bitcoin’s software rules limit the total supply to 21 million bitcoin.
Independent computers around the world verify transactions and enforce
the same rules.
🔒
Fixed Supply
Only 21 million bitcoin can be created under the network rules.
🌐
Decentralized
No single company, bank or government operates the network.
🔑
Self-Custody
Private keys can provide direct control without an intermediary.
⏱️
Long Record
The Bitcoin network has operated continuously since 2009.
⚠ Bitcoin is highly volatile and risky.
Its market price can fall by 50% or more. Past recoveries do not
guarantee future results.

Security and Privacy
🔑 The Most Important Rule
“Not your keys, not your coins.” Bitcoin left on an exchange is a
claim against that company. Self-custody means controlling the
private keys yourself.

risk after completing your own research.
