You don’t need to acquire a whole bitcoin to own Bitcoin.
Just as a US dollar is made up of 100 cents, a bitcoin (1 BTC) is made up of 100 million smaller units called satoshis or ‘sats’.
If 1 BTC = $20,000, then 1¢ = 50 sats.
If 1 BTC = $1million, then 1 satoshi = 1¢.
Anyone with even the smallest amount of wealth can own Bitcoin, irrespective of a bitcoin’s worth.
Bitcoin is divisible.
