You don’t need to buy a whole BTC to own Bitcoin. Each Bitcoin can be divided into 100,000,000 satoshis.
In other words: 1 BTC = 100,000,000 sats. The smallest unit of Bitcoin is named after its creator, Satoshi Nakamoto.
☝️ So even when the price of one BTC is high, you can still buy, receive, or mine Bitcoin in very small fractions.
