Many people think that Bitcoin is too expensive and that they can't afford a whole one. In fact, this is a big misunderstanding.

You don't need to buy 1 BTC; buying 0.01, or even 0.001 is completely fine. The key is that you own Bitcoin, not the quantity you have.

There is a psychological phenomenon called "unit bias" — people prefer whole numbers. For example, you would rather see "2.0 ETH" in your wallet than "0.400515 BTC", even if the latter is worth more. This is also why many coins are designed to have billions of units, giving people the feeling of "I bought a million coins."

But the truth is: **The number of coins itself is not important, what matters is the dollar value you invest.**

If you invest $200 to buy BTC, and BTC rises by 10%, you earn $20. Whether you own 0.005 BTC or 5 BTC, the algorithm is the same.

There is another detail - the smallest unit of BTC is 1 satoshi, and 1 million satoshis = 1 BTC. When the price of BTC skyrockets, using satoshis for pricing will be more intuitive. For example, instead of saying "0.00001 BTC" for a cup of coffee, you can just say "1000 satoshis".

In simple terms: **Don't be misled by the price of the coin; focus on the USD return rate, not the amount of coins held**.
