Where Our Data Comes From

Last updated: November 1, 2026

Prices: two sources, checked every minute

Live price: for the ~300 biggest coins, the price is Coinbase's live spot price, refreshed every 60 seconds. Pages update it in your browser every 30 seconds without reloading.
Checked: that price is compared with CoinGecko, which averages hundreds of exchanges. A green ✓ means both agree within 1.5%. If they disagree by more than 3%, we do not use the Coinbase price and we show an orange ! with both numbers, so you never see a doubtful number without a warning.
Other coins: priced by CoinGecko, refreshed every 15 to 30 minutes. Every coin page shows the source and the exact time of the price.
Market cap, volume and supply come from CoinGecko. Market cap and the 1h/24h/7d changes are re-calculated with the live price.
Left out of the ranking: tokens with a huge listed value but almost no trading (for example tokenized loans), because their market cap can't be confirmed. Their pages still exist, marked with a warning.
Late data: if our feeds are more than 30 minutes late, every page shows a warning banner. If there is no data at all, the page says so instead of showing empty numbers.
Charts: from Binance or Coinbase market data (CoinGecko as backup). The last point of every chart is the live price.
Other currencies: EUR, GBP, CAD, AUD and others use live exchange rates.

Crypto weather is the change in the value of all crypto over 24 hours: Sunny (up 3%+), Mostly sunny (up 0.75%+), Calm, Light rain (down 0.75%+), Stormy (down 3%+).
Is today normal? We measure how much a coin usually moves in a day (from its hourly prices over the last 7 days) and compare today's move with that. Less than its usual move = normal; up to twice = busier than usual; more = very unusual.
Safety check scores five things: size, how much is traded, daily price swings, distance from its highest price ever, and how many coins are still to be released. It is a simple guide, not a rating.
If you had put $100 in uses the coin's real price change over that time, before fees.
Price ranges on prediction pages are statistics based on past price swings, not forecasts.
