# Koinize

> Koinize is a data website about cryptocurrencies: live figures for the 500 largest coins
> (CoinGecko, read every 30 minutes) with a year of daily closes, 935 exchanges ranked by
> trust score (CoinGecko, daily), 289 blockchains by the value locked in their DeFi protocols
> (DefiLlama, hourly), and 200 guides to coins, exchanges, wallets, trading, security, DeFi, NFTs
> and crypto terms, in up to 21 languages (3,119 pages in all).

Every figure says where it is from (source, source_url) and when (as_of: the source's own time; read_at: when
Koinize read it). Money is in US dollars. Please give the source and the time when you quote a figure, and link the
Koinize page (url). The guides were written in 2023-2025: figures in their text are as
they were then; the live ones are in the API.
