Can You Buy Less Than One Bitcoin? How Fractional Bitcoin Investing Works

Can you buy less than one Bitcoin? Yes. You do not need to buy a whole Bitcoin (BTC) to invest in it. Bitcoin can be split into 100 million smaller units, so you can buy a fraction worth a few dollars. The smallest unit is called a satoshi, named after Bitcoin’s creator, Satoshi Nakamoto. One satoshi is 0.00000001 BTC, or one hundred-millionth of a Bitcoin. Major exchanges, including Coinbase and Kraken, support fractional Bitcoin purchases. Minimum amounts and fees differ between platforms. Fractions matter because Bitcoin’s price has risen a lot since 2009.
