# 104.4 Lesson - HighlyDivisible

**Screen:** HighlyDivisible

**Headline:** Special Characteristic

**Reward:** 3

**Text:** Old-fashioned fiat money can only be spent in amounts as small as one penny — or two decimal places for one US Dollar ($0.01).

On the other hand, Bitcoin can be divided 100,000,000 times over. This means that you could spend as little as ₿0.00000001. You will note the ""₿"" symbol, which is the Bitcoin equivalent of ""$"". Sometimes you will also see the use of BTC, instead of ₿.

By way of contrast, Bitcoin can handle very small payments — even those less than one US penny!

## QUIZ

**Question:** What is the smallest amount of Bitcoin one can own, or use?

**Answer:** 0.00000001 BTC

**Feedback:** Yes. You can divide a bitcoin into 100,000,000 pieces. As you already know, the smallest unit of bitcoin — B0.00000001 — is known as a “sat”.

**Correct:** true

**Answer:** One whole bitcoin. It is not possible to use anything less.

**Feedback:** Wrong. Bitcoin is highly divisible. You can easily use a very small fraction of a bitcoin.

**Correct:** false

**Answer:** 0.01 BTC

**Feedback:** Incorrect. Although the smallest unit of US currency is one penny, a bitcoin is divisible by much more than 100x.

**Correct:** false

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://earn.blink.sv/chapter-104-bitcoin-why-is-it-special/104.04-lesson-highly-divisible.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
