Do I need to know anything about Bitcoin to start?

Nothing at all. Lesson 1 starts at "what is money, actually?" and works up from there. If you've sent a text message, you can do this.

Is Bitcoin too expensive to buy?

Bitcoin is divisible into 100 million satoshis. A dollar buys you thousands of sats — a fully owned slice of the network. There is no minimum purchase.

The Bitcoin network has run continuously since 2009 without being hacked. The risk is operator error — using bad custodians, losing keys, falling for scams. The course covers all of it.

What makes this different from other Bitcoin resources?

Most resources are written by traders, for traders. This is written by one person trying to teach her parents — calm, clear, no shilling, no charts.

Is this financial advice?

No. It's education. Nothing here tells you to buy, sell, or hold anything. The lessons explain how Bitcoin works so you can decide for yourself.

Is the app available on Android?

Not yet — iOS only at launch. Android is on the roadmap.

Do I Need to Buy a Whole Bitcoin?

No. This is one of the most common beginner misconceptions about Bitcoin.

The short answer

You do not need to buy a whole Bitcoin. Bitcoin is divisible into 100 million smaller units called satoshis, or sats. That means you can own $5, $10, or any small amount of Bitcoin if you choose to buy.

1 BTC = 100,000,000 sats

A satoshi is the smallest unit of Bitcoin.

Why this confusion happens

Most price charts show the price of one full Bitcoin. When beginners see that number, it can feel like Bitcoin is only for wealthy people. But that is like saying you cannot use dollars unless you have a full million.

Whole coins are just one way to measure Bitcoin. For everyday learning, sats are usually easier. Instead of thinking “0.00025 BTC,” you can think “25,000 sats.”

Think in sats, not whole coins

$25a beginner test purchase

$100still a fraction of one BTC

Exact sats depend on the current Bitcoin price. Use the sats converter to see the live estimate.

How many sats can a few dollars buy?

Move the amount and watch the sats change. You still do not need a whole Bitcoin.

Approximate sats

10,160 sats

Fallback estimate: 1 BTC = $98,421.00. Prices move, so treat this as a learning estimate, not financial advice.

What beginners should focus on instead

The first goal is not to own a whole Bitcoin. The first goal is to understand what Bitcoin is, how ownership works, and how to avoid the mistakes that make people lose money.

Beginner questions

Do I need to buy a whole Bitcoin?

No. You can buy a small fraction of a Bitcoin. One Bitcoin is divisible into 100 million satoshis, so beginners can start with a few dollars if they choose.

What is the smallest unit of Bitcoin?

The smallest unit of Bitcoin is a satoshi, often called a sat. One satoshi equals 0.00000001 BTC.

Is Bitcoin too expensive for beginners?

A whole Bitcoin can be expensive, but a whole Bitcoin is not the minimum. The better beginner question is how many sats you want to learn with or own.

How much Bitcoin should a beginner buy?

This is a personal decision, not financial advice. If you buy at all, start with an amount small enough that you can focus on learning rather than price swings.
