Legal, disclaimers & privacy
over21m is a personal, educational project. The charts and commentary on this site are for information only and are not financial advice.
The short version
- Everything here is for education. None of it is investment advice.
- The data comes from my own Bitcoin node on a best-effort basis and can contain errors.
- Analytics are aggregate and cookie-free, your email is only used for over21m updates, and I never sell your data.
Not investment advice
Nothing on this site, including charts, commentary, or metrics, should be interpreted as investment, trading, tax, or legal advice. over21m does not know your individual financial situation, risk tolerance, or objectives. Always do your own research and, if needed, consult a qualified professional before making financial decisions.
Data, methodology & limitations
The charts and metrics published here are derived from a personally operated Bitcoin node and related databases. While I do my best to keep the data accurate and up to date, all views are provided on a best-effort basis and may contain errors, omissions, or delays.
- Blocks, UTXOs, age bands, and PnL are computed from locally stored data.
- Historical values may be revised if bugs are found or methods improve.
- Realized profit and loss estimates are based on my methodology and are approximations, not audited records.
No client relationship
Using this site does not create any advisory, fiduciary, or client–provider relationship between you and over21m. I do not manage funds, accept deposits, or execute trades on behalf of others.
Privacy & analytics
This site uses lightweight web analytics to understand aggregate usage (for example, which pages are most visited and which features people use). The goal is to improve the project, not to track individuals.
- Analytics run on Umami, hosted on my own server. It counts page views and button clicks without cookies and does not build a profile of you.
- If you sign in, one cookie keeps you signed in for up to 30 days. It is not used for tracking.
- The sign-in form uses Cloudflare Turnstile to keep bots out.
I do not sell your personal data. Any email addresses you provide for updates are used only to send project-related announcements and can be removed at any time via unsubscribe links or by contacting me.
Third-party links
From time to time, this site may link to third-party services (such as exchanges, wallets, or other analytics). These are provided for convenience only. I do not control and am not responsible for their content, policies, or security.
Changes to this page
As the project evolves, this page may be updated. When material changes are made, the “last updated” date will be adjusted.
