_About Us

We believe Bitcoin is one of the most important assets of our time, providing investors with a reliable and secure store of value. However, one of the biggest challenges is that Bitcoin's volatility creates uncertainty, especially for those unfamiliar with the way the market trades and moves.

At checkonchain, we help you navigate this volatility, by bringing together over 6 years of Bitcoin market analysis experience, and a unique perspective rooted in the study of Bitcoin’s blockchain data (onchain analysis). We provide traders and investors with expert guidance on current events, as well as frameworks for making data-driven decisions.

Our mission? To provide unmatched Bitcoin education and insights, helping you look ahead and respond to market moves with confidence. Think of us as your Bitcoin Personal Trainer.
