How does Bitcoin compare to similar coins?
The table below compares Bitcoin with the 3 most similar coins CoinPaprika tracks, using aggregated market-cap and rank data.
| Coin | Token | Market cap | Rank |
|---|---|---|---|
| Bitcoin | BTC | $1.64T | #1 |
| Ethereum | ETH | $292.39B | #2 |
| BNB | BNB | $96.45B | #4 |

What are the risks of holding BTC?
Cryptocurrencies including BTC are highly volatile: prices can move sharply in either direction within hours, and past performance is not a guide to future returns. BTC is currently trading 35.34% below its all-time high of $126,173.18, reached on Oct 06, 2025.
Only an estimated 20.10M of the maximum 21.00M BTC supply is currently in circulation, so further issuance could dilute existing holders. A meaningful share of BTC's reported trading volume comes from lower-trust exchanges, so headline volume figures may overstate real, organic demand. This is not investment advice.

How to buy Bitcoin (BTC)
- Pick a liquid market. Batonex currently reports the highest BTC volume among tracked exchanges (~$942.37M in 24h); compare order books on a couple of venues before committing funds.
- Check the Trust Score. Review Bitcoin's Trust Score, where available, to gauge how much of that volume looks organic before sizing a position.
- Place the order. Fund the account, choose a market or limit order, and confirm the trading pair matches the BTC you intend to buy.
- Self-custody if holding. For anything beyond short-term trading, withdraw BTC to a wallet you control rather than leaving it on the exchange.
Bitcoin FAQ
Bitcoin (BTC) is priced at $81,352.07 as of Oct 23, 2026, with a market cap of $1.64T and a rank of #1 among tracked cryptocurrencies. Over the past 24 hours the price has moved -1.72%, on reported volume of $24.65B.
Bitcoin's Trust Score is 53/100 (grade D, "Weak"), based on 2 of 5 planned components, the ones with live data today. Individually, liquidity scores 76/100 and volume authenticity scores 45/100. It is recomputed every 5 minutes under methodology v1.0 and reflects market structure, not a guarantee of project safety.
BTC trades on 2149 markets tracked by CoinPaprika. The highest-volume venues are Batonex ($942.37M 24h volume), UZX ($758.46M 24h volume), and Ourbit ($755.88M 24h volume). Compare fees, available pairs, and each exchange's Trust Score before choosing where to buy.
BTC's all-time high is $126,173.18, reached on Oct 06, 2025, and its current price of $81,352.07 sits 35.34% below that peak. CoinPaprika does not publish an all-time low for comparison, so the all-time high remains the clearest long-term price benchmark available for BTC.
BTC's circulating supply is estimated at 20.10M BTC, derived by dividing its $1.64T market cap by its $81,352.07 price. CoinPaprika does not publish a directly-reported circulating supply figure for every coin, so this is a calculated estimate, not an on-chain count.
CoinPaprika scores BTC's volume authenticity at 45/100. About 45% of its reported 24h volume is rated authentic, judged per market from exchange Confidence scores, volume against order-book depth and price against the consensus price. A meaningful share of that volume may not be organic, so treat headline volume with caution. This is one of 5 planned Trust Score components.
