About Us
An analytics platform: tools and a database for crypto holders and investors. We collect, verify and structure market data so you can make decisions based on facts, not hype. The project has been running since 2017.
What you get
- 15854 cryptocurrencies and 1475 exchanges in a single database, updated 24/7.

Data & methodology
Data comes from public sources, exchange APIs and on-chain data, and is updated 24/7. Holder Rank and exchange ratings are computed with a transparent methodology based on volume, liquidity, operating history and other objective parameters.
How we make money
Holder.io is free. We earn from exchange affiliate links (our main partner is Bybit, plus OKX, MEXC, Bitget, BingX, KuCoin, Gate): when you sign up through our link, the exchange pays us a commission, and you often get a welcome bonus. Affiliate compensation does not influence our data, ratings or Holder Rank — the rating is calculated algorithmically and is not for sale.
Our mission
Decentralized finance carries a wary reputation — driven by frequent scams, fake promises of outsized returns and poorly made decisions. We believe open information about project creators, coin history and price dynamics helps market participants avoid mistakes. Holder.io's goal is to make the industry more transparent and its participants better informed, by providing objective data.
