FAQ

Is it really free?

Yes. There is no subscription and no "premium" version. Ads pay for the site.

Where do the prices come from?

The converter and the prices page use CoinGecko, which averages many exchanges, refreshed every 5 minutes. The Telegram bot uses Bitstamp's prices, the same source as BITSTAMP:BTCUSD on TradingView.

Can I rely on them to buy or sell?

They are market information, not investment advice. The price you get on an exchange may differ a little, and there are fees.
