Bitcoin’s high price (often exceeding $60,000 per coin) might seem intimidating to new investors. However, you don’t need to buy a whole Bitcoin—you can purchase fractions of it, just like buying fractional shares of stocks or small amounts of gold. This guide explains how to buy satoshis (the smallest Bitcoin units) and highlights trusted platforms for retail investors.
Why Buy Fractions of Bitcoin?
- Affordability: Each Bitcoin divides into 100 million satoshis (0.00000001 BTC), making micro-investments possible.
- Flexibility: Invest any amount, from $10 to $10,000, without needing the capital for a full coin.
- Diversification: Allocate funds gradually, reducing risk compared to lump-sum purchases.
Bitcoin Units Explained
Bitcoin uses decimal-based denominations for precise fractional ownership:
| Unit | BTC Equivalent | Common Use Case |
|------------|-----------------|--------------------------|
| 1 BTC | 1.00000000 | Standard unit |
| 1 mBTC | 0.00100000 | Milli-Bitcoin (1/1000th) |
| 1 bit | 0.00000100 | Micro-Bitcoin (1/1M) |
| 1 satoshi | 0.00000001 | Smallest unit ("sats") |
