Hi Product Hunt! 👋

I’m Pratyush, the maker of CoinFinHub. I built it because most crypto platforms show you a number and leave the rest to you. An unusual price on one exchange can look like a genuine market move, while a market cap based on unchecked supply can look as reliable as a verified one.

CoinFinHub does the checking for you:

• Prices are checked across available exchanges, and coin pages clearly show when markets disagree or a coin is listed on only one exchange.

• Market cap and rank appear only after circulating supply has been checked against public sources. Until then, you’ll see “Supply not checked yet” rather than an estimate.

• Every move comes with context: is the coin moving with the wider market or on its own, is today’s volume unusual, and does the weekly trend follow or reverse the monthly direction?

CoinFinHub is free, requires no account, and keeps your watchlist, currency and theme on your own device.

For developers, we also released free, open-source Web Components for price cards, coin lists, tickers and currency conversion. Add them with one script tag, with no API key, account or dependencies.

I’d love to hear what you check before buying a coin and what CoinFinHub should help explain next.
