How the Live Price Feed Works

Behind every conversion sits one number from CoinGecko: a volume-weighted average price compiled from dozens of exchanges worldwide. Rather than quoting a single platform, CoinGecko pulls order-book data from every major exchange trading a coin, weights each venue's price by how much volume it actually processes, and produces one aggregate figure meant to represent that coin's fair market value at that instant. That is the number you see here when you convert, say, 0.5 BTC to USD.

It is a genuinely useful reference, but it is not the exact price you will pay or receive on any single exchange. Concrete example: if the aggregate shows 1 BTC = $60,000 and you convert 0.5 BTC, the tool reports $30,000. Sell that 0.5 BTC on an actual exchange and you will typically get a little less, for three reasons. First, every exchange runs its own order book with a bid-ask spread — the price buyers offer sits slightly below what sellers ask, and the aggregate lands between the two. Second, exchanges charge a trading fee (commonly 0.1%-0.5%) that this converter does not include. Third — and often the biggest factor on larger trades — is slippage: a big sell order eats through the order book from the best available price downward, so the average price you actually receive drops as the order size grows. A $50 trade barely slips; a $500,000 trade against thin liquidity can slip several percent.

Conversion works in every direction — coin to fiat, fiat to coin, and coin to coin — across the roughly twenty largest cryptocurrencies against USD, EUR and TRY. Prices refresh from CoinGecko and are cached in your browser for a couple of minutes, so repeated conversions do not hammer the free API; the timestamp under the result shows exactly how old the snapshot is.

What to Know Before You Trust the Number

Crypto markets never close: trading runs 24 hours a day, seven days a week, across every timezone, with no closing bell to pause price discovery overnight the way stock markets effectively have. That also means volatility does not rest — a figure from a few minutes ago can already be meaningfully out of date during a fast-moving news event. Treat every number here as an honest ballpark, not a locked-in rate.

This is a unit converter, not a trading terminal, a wallet, or financial advice. It does not execute trades, hold funds, or recommend buying or selling anything — crypto assets are volatile and can lose value rapidly, and any investment decision is yours alone. Before an actual transaction, always check the live quote inside your exchange or wallet app: that number already reflects that venue's own spread, fees and available liquidity, and is the one you will actually be held to.
