Imagine you are saving up for a really cool bicycle. You have two choices for where to keep your money: a digital piggy bank called Bitcoin or a traditional piggy bank filled with dollar bills. Over the last twelve years, something very strange has happened. The money in the Bitcoin piggy bank grew very fast, while the money in the dollar piggy bank actually bought fewer things over time.
Why did this happen? It all comes down to two big ideas: scarcity and inflation.
The Bitcoin Story: The Digital Treasure Map
Bitcoin is like a rare digital treasure. When it was created, the rules stated that there would only ever be 21 million Bitcoins. No one can ever change this rule, not even the smartest computer programmers in the world.
Because Bitcoin is rare, and more people want to own it every year, the value goes up. Imagine a popular new toy that only 21 exist in the whole world. Everyone would offer more and more money to get one! Bitcoin works the same way.
The Dollar Story: The Magic Printing Press
Now, look at the US dollar. The government has a "magic printing press" that can make as many new dollar bills as they want. When the government spends money on things like building bridges or schools, they sometimes print new money to pay for them.
When there is suddenly a lot more money in circulation, each individual dollar is not as special anymore. It takes more dollars to buy the same candy bar or toy. This is called inflation. Think of it like this: if you have a huge balloon filled with air, and you keep blowing more air into it, the air inside becomes less precious because there is so much of it.
Summary: Why the Value Changed
- Bitcoin increased in value because it is scarce. There is a limited amount, and more people want it.
- The dollar decreased in value because of inflation. The government can make more of them, which makes each dollar buy less.
Understanding these two rules helps you know why it is important to think about what kind of money you are holding!
