What is the minimum amount to buy bitcoin?

The minimum amount to buy bitcoin depends on the platform you use, because bitcoin itself can be split into tiny pieces. Most consumer apps let you type in a dollar amount and give you the matching fraction of a coin. As of November 2026, the smallest purchases on several major US apps are a dollar or two.

You do not need to buy a whole coin. A bitcoin is divisible down to its smallest unit, the satoshi, which our guide on what is a satoshi explains. Platforms then set a floor for each order to keep processing practical. That floor is a business choice by the company, not a rule of the bitcoin network, and it can change.

What is the minimum bitcoin order on an exchange like Kraken?

Trading screens often set minimums in bitcoin rather than dollars. Kraken's support page says a BTC order on its trade form must be at least 0.0001 BTC, while its Buy Crypto button may accept a lower minimum. A separate cost minimum also applies by quote currency, for example 0.5 for orders priced in US dollars. Orders below it are canceled with a "Cost minimum not met" error. Kraken notes these values can change without notice, so the account screen shows the current figures.

Do small bitcoin purchases cost more in fees?

They can. Many apps charge a fee or spread on each buy, and fixed or tiered fees take a larger share of a very small order. Network fees also matter if you later move small amounts off the platform. See what are crypto fees for how these charges work.
