At the market price, before fees. An exchange will give you slightly fewer sats than this.
You don't need to buy a whole bitcoin
Bitcoin splits into 100 million satoshis, so any dollar amount buys some. That's why amounts of bitcoin often look tiny: $100 is usually a small fraction of one BTC, which is easier to read as sats. Read can you buy a fraction of a bitcoin?
How costs change the answer
The table shows the market rate. What lands in your account is lower:
- Flat fees hit small buys hardest. A $0.99 fee is 9.9% of a $10 purchase but under 0.1% of $1,000. Many exchanges also set a minimum purchase.
- Percentage fees and the spread cost the same share at any size, so on larger amounts they're what matter. Compare the order preview, not the headline price.
- Withdrawing to your own wallet costs a network fee in sats that doesn't depend on the amount. Moving $20 of bitcoin on-chain can lose a noticeable share to fees.
The true cost calculator works it out for your numbers. If you plan to buy a fixed amount regularly, the recurring purchase simulator shows how the average price works.
"Sats per dollar"
Some people track bitcoin the other way round: how many sats one dollar buys. It's the same information as the price, just inverted (100,000,000 ÷ the BTC price). When the bitcoin price rises, a dollar buys fewer sats. See what $1 buys.
Why the rate differs between exchanges
CoinGecko averages bitcoin prices across many exchanges, weighted by volume and with outliers removed. Your exchange quotes its own price, which is usually within a fraction of a percent of that average in calm markets.
How to check a price safely
- Go to the source yourself. Type the address of your exchange or a big price tracker, or use a bookmark. Search ads and links in messages can lead to copycat sites.
- A price is never a reason to rush. "The price is about to jump, buy now" is the oldest pressure tactic there is.
- Fake trading sites show fake numbers. Scam "platforms" display made-up prices and balances that seem to grow, then demand a "tax" or "unlock fee" before you can withdraw. If you can't withdraw, the balance isn't real. Read how to spot fake crypto trading sites.
- Checking a price never needs your wallet. No converter, this one included, should ask you to connect a wallet, sign anything or type a seed phrase. Anything that does is a scam.
