Where bitcoin trades

Centralised exchanges (CEX)

Centralised exchanges (CEX) are companies. You sign up, verify your identity (KYC) and they hold the coins for you until you withdraw them. Easy to use, but while coins are on the exchange they are not fully yours.

DEX and peer-to-peer (non-custodial)

Decentralised and peer-to-peer venues have no company holding your coins. You trade from your own wallet or directly with another person, usually without ID checks. More control, more responsibility.

THORChainswapNoSwaps native BTC with other coins without wrapping, through apps built on THORChain. Fees and slippage vary.
Uniswap (WBTC / cbBTC)swapNoTrades wrapped bitcoin tokens on Ethereum and Base, not real BTC. WBTC and cbBTC are IOUs backed by custodians, so you rely on them.

Approaches to buying

DCA: regular buying

Buy for the same amount on a schedule, say every month, whatever the price. You don't try to guess the bottom, and the average price smooths out over time. Works well with automatic recurring buys. Try the calculator below.

Lump sum

Put the whole amount in at once. If the price rises afterwards you gain more than with DCA; if it falls you feel the whole drop. History shows both outcomes. It's mostly about how much volatility you can live with.

Buying on drawdowns

Keep cash aside and buy only after the price has fallen, for example 20–30% from a recent high. It can lower your average price, but drops may not come when you expect, and you may sit in cash while the price climbs.

HODL + cold storage

Buy, move the coins to your own hardware wallet and hold for years, ignoring daily moves. Fewer decisions, fewer fees, and no exchange risk. The key task is keeping your seed phrase backup safe.

Caution: leverage and perpetuals

Leverage lets you trade with borrowed money. At 10x, a 10% move against you wipes out your stake (liquidation), and BTC often moves that much in days. You also pay funding fees and never own real bitcoin. Many leveraged traders lose money.

Bitcoin launched in January 2009, but it had no market price until mid-2010 (first exchange quotes in July 2010; this dataset starts on 2010-08), so the slider starts in 2010.

Assumptions: one buy on the 1st of each month at that day's price (first available price for 2010), no fees, no taxes, coins never sold. Current price: $82,494 (2026-10-09 21:42 UTC). Price history: blockchain.info charts/market-price (timespan=all, daily USD).
