CoinCodex

For a quick comparison, choose the market-table period and the number of coins displayed before looking at gainers or losers. The default set can hide smaller assets. CoinCodex calculates cryptocurrency prices from volume-weighted market prices, while market capitalization uses circulating supply. It may omit a market cap when that supply figure is unavailable or unreliable.

Build a personal holdings view

1. Open Portfolio and choose Add Coin.
2. Select the cryptocurrency and enter the quantity you hold.
3. Add further coins, then choose the period for the performance view.
4. Use the pie-chart icon for Portfolio Overview, or the eye icon to hide amounts while leaving percentage changes visible.

Holdings can be edited or removed later. The mobile apps also provide portfolio views and home-screen widgets. This is a record of quantities you enter, rather than custody of the coins.

Watchlists use the star next to a coin. Price alerts offer a separate way to follow a level without repeatedly checking a chart. Public prices and portfolio instructions are accessible without paying to read them.

Prices and predictions serve different purposes

Historical charts describe market observations; algorithmic prediction pages are estimates. A prediction is not a price available for a trade. CoinCodex itself is an information service, so buying or selling requires a separate provider.
